The Contact Information dialog (loaded from User Context Menu, View Contact Info...), displays a dialog for editing the user's nickname and and viewing personal information, current status, client information, location, and other specifics.
Group management is accessible via the Edit Groups dialog (available from User Context Menu, Edit Groups...).
To find out all of the little details about a person on the roster, the Contact Information dialog is where to do it. Everything from their presence and status to their email address to their birth date to their operating system is listed within the tabs of the Contact Information dialog.
Above the tabs are two important fields that list the person's Jabber ID and their resource. Use the drop down box to fetch resource specific information such as presence, GnuPG signature and client information.
The General Info, Personal Info, Location, Organization and About tabs provides current vCard information (full name, email address, address, web site, etc.) about a user. This information is submitted through the user's client. Gabber provides editing of vCard information from the My Information dialog. The value of the Nickname field is used for display in the roster and in messages. The nickname field is edit-able.
In addition to vCard information, the General Info tab shows two valuable bits of information. Exact status (or "away") messages given by the user are listed in the Presence and Status text area. This status information is set in Gabber through the Status toolbar (see the section called Status in the chapter called Main Window for more information). Below is a small icon that provides information about the GnuPG signature of this user. Hovering over this icon will indicate if the user has signed their presence and is thus able to receive encrypted messages. If the person did sign their presence, clicking on this icon will provide information on the signature. See the section called Encrypted Messages in the chapter called Messaging & Chatting for more information about signatures and encrypted messages. Another useful bit of information is found in the Subscription area where the current status of subscriptions with this user is displayed. the section called Subscriptions explains subscriptions in greater detail.
The Client Info tab shows information queried from the user's client application. If no information is shown or if the fields are blank, the user's client does not support that type of query.
The context sensitive Edit Groups dialog allows users to be easily added and removed from groups. At the top of the dialog the user's nickname and JID is listed for reference. The left side of the dialog lists groups that the user currently belongs to. Using the central Add and Remove buttons, the user can be added and removed from the available groups on the right side of the dialog by selecting a group in one of the two lists and clicking the appropriate button. To add a new group, simply type the name in the Group text box and click the Add button.
