i was thinking if you made a vip area and the vips would get like the admins mute,kick,(tele to other players),weapons
and use of the tank and other vehicles and there weapons.
you could have a pay thing by credit card
like
$3.00 = 1 mounth (of vip)
$6.00 = 2 mounth (of vip)
$9.00 = 3 mounth (of vip) and so on
and you could make a profit out of it...
but that is just a suggestion.
