It's not that it's that important. It's that the thread was there, it disappeared, it reappeared in another folder (but without the "moved to" notification that usually happens when a thread is moved - and none of the mods moved it), it disappeared again, reappeared, disappeared, Ticia found it and said it was in the Coffee Break folder, and now it's gone again.
There's something wrong with the software, it sounds like. None of the mods or Admin have been able to figure out what's happened. If it happened to this thread, it could be happening to others. It could explain some of the other threads and posts that people are noticing going into a black hole somewhere. There have been other posts that just disappear (and weren't removed by mods, so it wasn't like a forum rule type issue). So it might need to be looked into.
