If there were a "contact webmaster" or "contact us" link I would have used that (I did have a look) but since there isn't one, where else would you propose to ask this kind of question? It's ok to say use private message, but let's think that option through for a second. If we assume I don't have prior knowledge of who makes changes to accounts on this forum, how would I know who to private message? As it happens, I don't know who I would contact. The only person I can think of is Nigel, because I know he moderates this forum... but can he make account changes and stuff? Not sure.
