To explain, it helps us focus discussion when there isn't always a whole lot of flexibility in what can be discussed. This is especially true in regards to games that have yet to be released - the threads in the AQ3D forum are pretty much the only things about the game that can be discussed at this point. :P
I was beginning to think they would implement something like this in the AQW forums...or any of the forums with people who tend to make really bad threads
