[Juser] (no subject)

Hi, I started using jabber today. I have successfully registered a new 
account but am having one problem:

I'm having difficulties adding members to my jabber roster that are on 
other protocols (msn, aim, etc.). I've checked the agent browser in my 
jabber client (JabberFox, OS X) and the relevant agents are active. I 
believe the problem I'm having is determining the correct user name 
needed to successfully connect with the other user. Is there a standard 
syntax for usernames on other protocols?

Could anyone help?

Many thanks, Lief Stryder.
