And making a thread in General Business won't annoy them? I think it's best just to wait and a mod will notice it from you reporting it. Have you checked if any mods are online?
Can you not just post again afterwards stating your mistake....as long as your not bumping the thread?? People will understand as long as its a valid change..not just a spelling mistake!! lol EDIT: OK, you posted that at the same time as me, so maybe getting in touch via PM (see the groups page to see who to contact) will work.
Maybe a direct PM if it's a case of emergency... Check the link below http://forums.digitalpoint.com/showgroups.php
Then perhaps you should drop a shoot a PM to Rob, Smyrl or Sarah as I see them online quite often and actively moderating, too. Kindly explain the situation. They should be able to help you out.
