don't give your account away, sir, let us remember you for you.
also, if you REALLY are leaving for good, you'd better make a new email address so you can't recover your password.
although, i don't want you to leave, i'm just trying to help make leaving a reality.
make sure you don't give your account over to some n00blet, that would sadden me :(
farewell sir, maybe we will hold a vikings funeral or something :P
