Before you begin
The actions that you can perform on a stand-alone forum topic depend on your role in the forum and whether you created the topic. The Forums administrator has access to work with all content in the Forums application. Only forum owners and topic authors can edit, move, and delete forum topics. Anyone with access to a forum can mark content in that forum as inappropriate.
In a community forum, any member of the community can reply to a forum topic or flag a forum topic as inappropriate. Only topic authors and community owners can edit, move, and delete community forum topics and topic responses.
