I have moved this thread here, as it is a better fit than our "Introductions" forum.
We typically do not delete user accounts on request, unless there is a compelling reason to do so. If you truly wish for your account to be deleted, and you have such a reason, please PM one of the MHB Administrators to explain why you wish for your account to be deleted. Even if such a reason is given, your posts would most likely not be deleted as that could leave certain threads gutted and useless.
If it is simply the case where you are finished with math, and will no longer be asking for help, then we would prefer to leave your account active...and who knows, you may find you wish to post here again and that way you will not have to register all over again.
