Deleting an Account
When you delete an account, you need to decide what to do with the account's
files. Remember that you can disable the account instead of deleting it. If
there's a chance that the account will need to be activated in the future, you
should just disable it (de-select "The account is enabled" on the screen
containing the account's information). If you're absolutely sure that no one
will need the account in the future, then you may want to delete the account.
