[powerful_rogue]

if ($_GET['do'] == 'removewarning')
{
if (!can_moderate() || !$vbulletin->options['can_del_warn'])
{
print_no_permission();

Using the above it shows this feature to mods, super mods and admin. Id like to change it so it only shows to super mods and admins.

(!is_member_of($bbuserinfo, 5,6)

Am i working along the right lines if I change the part in bold to the above?

Also, can anyone help with what the ! is for?
