Now you can get on with the traditional method, but you can't see buddies which are using the different login server than you - you both have to be on the same, either scs.yahoo.com or scs.msg.yahoo.com.
Thats a very nice piece of information there. I had the same problem, but couldnt guess why my buddies were shown offline, now i know the reason. There is a catch here...in gaim 0.74, usually you cannot connect to yahoo with scs.yahoo.com, you will have to change it to scs.msg.yahoo.com to get online. (This is there in the gaim FAQ:http://gaim.sourceforge.net/faq.php#q58
This is solved with the new gaim 0.75 which automatically updates the server to scs.msg.yahoo.com.
I have a new problem here, when i updated from 0.74 to 0.75, i am not able to connect at all...it says "Your account is deactivated" !!! I dont know what that means, i am able to connect to yahoo from a XP machine. I am guessing it is the profile that is causing the problem, i think by deleting theextra profile this will be solved.
Coming to yahoo messenger for linux, too bad it doesnt have socks support, so i cant use it. I'm presently working on runsocks to get yahoo working
A piece of advice *DONT EVER MENTION ALIAS IN YAHOO*
