SMFShop is a Shop MOD for Simple Machines Forum. Members of your Forum will collect credits every time they make posts, and can exchange the points for items in the shop (eg. Random Points, Add 100 to Post Count, Increase Karma, etc.). It is a standard package that you install into your forum using the 'Package Manager' (in the 'Admin' section).
