Can you get rid of the "LOL, someone else posted while you were typing, so we won't actually post this even though you fucking hit 'Post!!!'" issue? I tend to not notice the warning until I'm hitting Backspace to go back to the thread. Which means I lose the contents of my post.
In ten years of posting stupid shit on the Internet, I've never been on a forum before where such a warning is implemented, and it's fucking annoying, especially in threads that tend to get lots of rapid-fire updates at the time of day you're posting.
