Well because it's hard enough to get people to even read the threads that have a small paragraph. Do you really expect them to read something that is a page and a half long? If they won't read even one small thread there is no way in hell they are going to read a single huge thread. Not to mention everything is already in one area on the forum. It's the reference section and is the FIRST thing all of you see. The FIRST section is the reference section and it says PLEASE READ THIS FIRST! The first four threads...the ones the pop-ups ask new members to read are stickied to the top of the reference section. I don't think we can make it any more simple than that.
