[Wocky] Trying to connect to Jabber from iChat

[Greg Hudson]

iChat does not currently support new-style TLS negotiation, so you  
have to use port 5223 to use its "Connect using SSL" option which  
uses old-style SSL.  Clients with more modern Jabber connection code,  
like Gaim and Adium, can do TLS over port 5222.

The iChat instructions on http://itinfo.mit.edu/answer.php?id=8061  
appear to be correct, but I'm not sure if it's easy to find them.   
I'm guessing you adapted your iChat setup from the instructions for  
Adium.
