Someone known to me, has this handle, and its associated mail id (so ik that's him). This account was created a long time ago, and I would guess that the person hasn't done much CF, and created the account just for the sake of it, and then forgot. The guy logged in today, to find that the user is disabled. Is there a way to un-disable the account? And why was this imposed on this account?
