This is really weird, I have absolutely no options available under Buddies anymore. I just removed a Jabber Buddy by right clicking the name and doing it through the Context menu. The reason I did this is because the 'remove buddy' option was greyed out. Now i've done it, all the options are greyed out. I thought the reason may be because it was a Jabber Buddy but the situation is the same for others with AIM or MSN accounts (I used PSI to enable iChat to connect with MSN and Yahoo Buddies).
