Hey, I know this won't help you now.. But, GroupWise 6.5 has a cool package included with it called GroupWise Messenger.
It is essentially an instant messenger for corporate environemnts (They're not trying to compete with Yahoo)..
You setup the agent on one of your Novell servers, and can also set it up to use SSL encryption. Plus you can log everything.
The best thing about it, as opposed to using Yahoo, AIM, MSN, etc.. is that your data stays within your own network. It doesn't go out in clear text over the Internet. And, if you have remote users that ARE out on the internet, the encryption takes care of that. So your communications are always secure.
I would recommend this for ANY company that uses instant messaging.. On the downside, it is a little underdeveloped and doesn't have all the features you're used to, but i imagine it will get better. Even with SP1, they've added quite a few features.
