Please don't do things like this.
Threads aren't generally deleted at LQ. If you made a mistake, such as posting in the wrong forum, just use the "Report" button at the bottom of your post and ask the moderators to correct it for you.
If you managed to resolve your own problem, don't erase what you posted, but instead add a follow-up post explaining how you did it. Your experience may help somebody else in the future.
