If you are asking about the blue x's that show up next to a thread when viewing a topic forum, that means that thread is closed. Members can no
longer post replies.
its either because the topic of the thread is either being discussed or its something the the mods dont appresaite whether its something directed
towards them or bad mouthing the site but its usaully because the topic is already being discussed in other treads...the the one that will do it most
the time...so make sure that you really try everything you can think of in the search engine before you post a thread so you dont fll victim to th
thread being closed or getting a 404
