you shouldnt make it such a declaration.
leave the forum if you feel like it, come back around if you feel like it. its all the same really.
i do it every now and then. people here think i left, some welcomed me back, and im all "back? i was gone?" "yes, werent you?"
dont make such a big deal out of it. judging by some of the posts above, you are very probably welcome to return again
