Message counts would certainly be a good idea

Con't you mean PM?  I would like to have IM available so that if I see someone online I can send a message to their screen and perhaps invite them to chat.  I do not have to rely on whether or not they have AIM or other.

I see the add on for this, but do not know how to do the install!  Bummed!
