It is truly a thrill to use Trillian, and no I am not being paid to advertise this thing. But once in a while a great application comes along and you just want all your friends to know about it. This is a great application.
What is Trillian? It enables you to merge all your IM's into one location. For example, if you want to know what's happening in your facebook, hotmail, gmail and yahoo at the same time, then Trillian lets you know when your friends sign in and out, whether you just got mail, and it also allows you to make calls. There are so many pluses of using it, you just have to try it and judge for yourself.

If you are interested, and you should be, everyone I know is using it, and soon you can join us:

Let me know how it works for you....
