Setting up a Jabber account
Jabber accounts are unsual in that they are created through Proteus. The website http://www.jabber.org/ lists a series of Jabber servers, one of which you must pick.
How do I set up a Jabber account?
In Proteus, create a new Jabber account, listing your username in the format of username@server.org and being sure to insert the relevant data. Then, in the Account Options tab, ensure that the Host Name corresponds to your chosen host.
