America Online Online Gaming Forum (which is no longer in use) used to use volunteers chosen from applications from its users. These people were called OGFs by other members, and their screennames showed their role (i.e., OGF Moose, etc.). While users only needed to be members of AOL to use the Online Gaming Forum, OGFs were given powers like AOL "Guides" and could use them at will when they thought it was right.
