Yeh I was wondering the same.

Can someone confirm this for me (my understanding from reading this thread):

To get msn we use amsn right? or is there an out-of-the-box client for it?

to integrate with UI you need telepathy-haze right?

to use multiple accounts you need telepathy-butterfly?

telepathy-haze / telepathy-butterfly are in Extras-testing?

Extras-testing is full of possibly harmful software?

Thanks for any response!
