What a pity! Why do you feel you need to leave the forum? Those people who aren't happy just don't come any more but you could PM the Administrator to ask him to cancel your account if you prefer. You can't do it yourself. If you are just wanting to change your username, Admin can also deal with that. To use the PM facility you need to make one more post as it's only available to people who have posted 5 times. Do reconsider though and let us know what is wrong.
