There are plenty of good reasons to ask for one of your threads to be deleted. Maybe you have gotten the feedback you wanted and would like to work on it, or you're submitting it elsewhere, or you accidentally posted twice. So thread deletion requests come up often. Rather than making a new thread in the support/feedback forums when you'd like a thread deleted, please just send a private message (PM) to a staff member. After all, the idea is to have fewer threads! For account closure, please send a PM to an administrator.
