This forum is esentially just a web client for some D-specific newsgroups (and a number of folks access it via either the newsgroup interface or its associated mailing list rather than through the web interface). So, you can't edit or remove posts. Admins can remove spam from the newsgroup (and thus the forum), but that's pretty much it, and even then, that doesn't remove it from the mailing list, because you can't get an e-mail back once it's been sent. So, once you send something to the forum, it's out there forever.
