The GetShopped support forums plugin is used with bbPress to transform your forums into a support forum.
Pick and choose which forums you would like to turn into a support forum. Turning your forums into a support forum will display topic statuses that admin's, moderators and the topic creator can change. You can also implement a user ranking system through the forum settings. For extra functionality check out the GetShopped_support_forum_widgets.
This Plugin requires the new bbPress 2.0 plugin and will not work with their older versions you can find the bbPress plugin here: http://wordpress.org/extend/plugins/bbpress/
