Some time ago, I tried to set up an IM client on my Mac that would connect to my company's Sametime server. It might have been an older version of
Adium, or it might have been
Mercury. I can't quite remember. Either way, I couldn't get it to work, and just gave up. Well, I took another shot at it today, this time using the current version of Aduim, and it worked like a charm.
The official Sametime client for Mac is in beta right now. It looks pretty good, from what I've seen, but it's nice to have something that works well in the meantime.
