One more thing to add to the double posting thing, the boards for Drama (even though you probably won't go there) and Help don't have edit buttons, so think if you have put all of your thoughts and that you haven't made major spelling errors in your post before. And you can't lock in Drama, too.
The reason that we don't have edits in Drama is that someone edited all of their posts when their thread backfired, and the reason for no locks in Drama is that someone made multiple threads and locked the others after some backfiring.
There isn't really a reason I've heard of for no edits in help.
And it isn't really about bad grammar, just about if you can actually spell.
