[TECK]

chen, i did this:
i created 2 admins, userid 1 and 2.
i created 1 registered user, userid 3.
now, userid 1 can edit all users and userid 2 can edit all users except the ones listed in $caneditadmin.
i tested all and it works perfectly, in my test board, with the code above. you try it and let me know please. thanks.

update:
i also tried
$caneditadmin = '1,2';

now all admins can perform changes.
