I had an error this morning while creating a new thread. Seems like it always get to me when I'm trying to create a new thread. It times out, then I have to do it again--but then it gives me the duplicate thread error. That bugs me because the first thread didn't even go through. It must be queuing or something, but I go ahead and try to post it again but slightly changing the title of the thread (usually by adding a number next to it).
After that, I wait for the longest time before (if I'm lucky) it goes through.
