Disclosed are various approaches for facilitating reservation of a physical resource on behalf of a user. A physical identifier can be affixed to a physical resource. A directory service identifier can be embedded within the physical identifier. The directory service identifier can identify an email address or identifier to which reservation requests can be sent.

A system, method, and computer-readable medium for resolving an identity of an entity, comprising: parsing entity identifier information, the parsing generating entity identifier elements from the entity identifier information; classifying an entity identifier element with an entity identifier element type; normalizing an entity identifier element to provide a normalized entity identifier element; and, associating the normalized entity identifier element with an entity to resolve the identity of the entity.

Systems and methods for providing an enhanced managed email service are provided. According to the disclosed subject matter, the enhanced managed email service maintains a group folder for each defined email group. Rather than delivering a received email to the email folder of each member of an email group, upon receiving an email for distribution to a defined email group, the enhanced managed email service stores the email in a group folder corresponding to the email group for the entire email group. Email specifically identifying one or more recipients (in addition to group membership) is delivered to the specifically identified recipient(s). The enhanced managed email service maintains user access status with regard to the email in the group folder for each of the members of the email group. Email group members may access the email via the group folder.

A vehicle wheel overlay attachment system disclosed herein provides for wheel overlays, or wheel skins, that are readily installable over existing wheels by securing directly to a wheel center cap. The center cap is adapted to be inserted into the center hub portion of the wheel, much like a traditional center cap, but also contains a system for securing a wheel overlay to the center cap. When properly installed on the center cap, the wheel overlay will be snugly positioned over the wheel thereby changing the appearance of the vehicle wheel.

Collaborating on documents by e-mail may be streamlined into a unified process. In one example, a user creates a document in an online document service, and sends the document to collaborators by mailing a link to the document. The document may have permissions set so that the creator of the document, and any user on the e-mail distribution list, can read and edit the document. When a user receives the e-mail, that user may open and edit the document. Upon closing the editing application, the user may be presented with an appropriate interface to create a reply e-mail.

A system and method for migrating from the legacy SMTP protocol to an alternative email protocol, such as Bitmessage protocol, for sending email messages comprising a publicly accessible directory which associates the alternative email protocol addresses with an SMTP addresses of a particular recipient, and a server that accepts an outgoing message sent by SMTP protocol and routes the outgoing message via the alternative email protocol if recipient's SMTP address and a corresponding alternative email protocol address is found in the directory, and routes the message by SMTP protocol if no corresponding alternative email protocol address is found in the directory.

A server is configured to provide a service that manages access to communication sessions supported by at least one communication service and to which user devices connect. The service assigns to users registered with the service respective communication identifiers that the users, and unregistered users of the service, use to access the communication sessions via user devices. The service maps each communication identifier to a list of communication sessions, if any, in which the respective user is currently participating and/or is scheduled to participate. The service receives from a user device a join request from a requester. The join request indicates a particular communication identifier of a particular user registered with the service and a requester identifier. The service connects the user device to a communication session, if any, based on the particular communication identifier and the requester identifier.

Disclosed is a passwordless electronic mail (e-mail) communication method and system. The method includes receiving a cell phone number inputted by a user over a user communication device for registering the user with a server hosting a passwordless email service website with a domain name, sending a SMS message including a verification code to the user using Hypertext Preprocessor (PHP) APIs, authenticating the user communication device using the received verification code, and in response to a successful authentication of the user communication device of the user: converting the received cell phone number into a predefined text email address containing the cell phone number and the domain name, and facilitating the user with transmission and reception of e-mails globally, to and from another user using the converted predefined text email address.

Methods and systems for providing current email addresses or contact information to members within a social network are described. In one described method, an email program application requests an email address for a member within a social network. Using profile information associated with the member, the email address is provided to the email program application which sent the request. The email address is then entered into the send-to parameter field of an email message. In another described method, contact information associated with a first member of a social can be provided to a second member of the social network. The contact information is provided if the relationship between the first and second members is an authorized relationship. The contact information associated with the first member can be used to update the contact information for the first member in an electronic address book associated with the second member.
