I have never been a fan of these since the mid 1995s (with AOL). Now, I don't use them at all, but I do need to use them now, mainly Google
I know there are a couple that are integrated into a gew of them.
Basically, I would like to be invisible to most people. Which program will offer / suport this feature? I know there is Trillian and a couple of others. I downloaded GChat but I did not see how to be visible to only certain people. I just don't have the time to sign on and talk to 20 people.
