For some reason, if I leave the page of my post and open it again, I can no longer edit my post. Additionally, if I'm not signed in and go to the page of my post, it says "Page not found". I cleared cookies already. It's not a big deal right now, just wanted to put this out there as I don't think I'm the only one.
Okay, problem fixed. The topic I had posted didn't contain original content and contained a hyperlink, so the servers had to determine whether to take the post down or let it stay up. Sorry for the trouble!
