Imcom >however only supports jabber from what I saw...while centericq >supports a hole bunch of different protocols. That's only half true. Yes Imcom only supports jabber directly but jabber has gateways for all the other protocols such as icq msn aim etc. So you just have to find a jabber server with the transports you watn to use and then you're set as far as messaging goes. I didn't know that Centericq supported msn again. They remvoed it for a while so I wasn't sure. It's pretty much your preference I guess. I prefer imcom but it's a tiny bit more work to set up because you have to fidn a jabber server that has all the transports you need and you have to tell the jabber server to register you with the appropriate transports but that's not difficult and only needs to be done once.
