Previously my account on these forums was username Brighid. I made a mistake and created this new account not realizing I already had an Ubuntu One account (it's been a while). I saw directions in another thread to associate the old email with the new Ubuntu One account and I will try that to connect the other account.
I know some folks out there recommend not to rename the built-in administrator in Windows Server 2003. Instead, create another admin account with the same privileges and disable the built-in administrator account. But what if the situation is that I need to rename the administrator account?
After almost two years of being here (and a while of not posting) I have decided to request (if possible) for my account to be disabled. I'm planning to delete my Ubuntu One account, too, and disabling this account will seal the deal. I will be on the IRC channel from now on, though, but I have no use for this account here.
