"I agree with the idea of keeping the thread when someone wants to delete their posts and they are the very first post...good idea to just make that first post annonymous. When a poster want all deleted a mod could "hold" any posts that a person is the first poster in until they could look that post over, make it annonymous and "snip" out any information contained in the post that might have any type of info that might reveal an identity. Just think of some of the megathreads that provide much very valuable information...if they were deleted it would be a shame".
