Bah, I do not have trillian here, nor can I even get it here if I wanted to. as for posting where they know nothing about, when you find those posts just delete them, I do it all of the time. That button is how I was able to keep up with having a ton of posts to read and, like dan was saying, it prevented me from having to look in each and every catagory.
That is just my opinion tho.
