I regret getting sucked in to the politics board of this site, and so I'd like all the threads I started on their deleted, but no one appears to actively moderate that section so there isn't anyone to directly ask.
I think that provided your thread has fewer than, say, 40 replies, and within a certain timeframe, you should have the ability to delete your own threads yourself.
