If the account has *none* of the above entries (and would show up in maintenance/removeUnusedAccounts.php's report mode), then it's safe to delete them from the user table. Always make a backup of your database before manipulating it in this fashion, especially when the consequences are not clearly defined, as in this case. Rob Church
