How come there isn't a dedicated Halo Online forum here?
It is a legitimate question so I will supply an answer. This forum only supports Halo games that have company supplied and sanctioned editing kits. Halo PC, Halo Xbox and Halo Online do not have company supplied and sanctioned editing kits therefore we do not support them with dedicated forums.
As a courtesy we have supported limited (<3) threads about any of the Halo Games, usually when a new one is released, however the Halo online threads had become disruptive and discussion of the Halo Online game is now off topic.
