People who don't listen to others i.e. the 8 members of this forum I have put on ignore as they talk such utter **** all the time. This now includes the member who thinks they are a moderator.
I believe if you want to delete your account completely / remove all posts, you need to apply to one of the mods to do this for you.
(Never come across a web forum before where you cant delete your own account - but hey first time for everything).
