If you feel the need to leave a forum, just disappear quietly, that leaves your options open if you decide you were wrong and want to come back in the future....
if you feel the urge to go totally rank at people, as TL recommended, i recommend the pointlesswasteoftime forums:

edit: display extreme caution with any links/images you choose to follow on the pwot forums, i just got goatse.cx'd twice :/
