What do you want it deleted for anyway? We usually put abandoned projects in the Abanded Projects subforum, so that if you ever decide to work on it again we can bring it back out for you. Also, there should be a button that says delete at the very bottom of the topic. The one under your profile just deletes a post.
Also, @BoE, I don't think that the quick moderation settings are on by default. He'd have to go into his profile and chaange them for there to be an icon there.
