This accidental thread deletion has been a recurring, uh...thing for a bit now. So I'm simply suggesting that if you make what you think is a stupid post, rather than rolling the dice on which delete button is the one for the post and which one is for the thread (and that really is a game of chance, they change every few seconds, you know), just edit the post to read something like "post edited to remove stupid content rather than accidentally deleting the thread. Love, Larry."
Or just leave the stupid post, quote yourself, and then say, "oh, that was stupid. Never mind!. Peace, Larry".
Just don't delete no more threads if you keep from it. I don't know that it's necessarily stupid to delete these threads, but it's not pretty.
