I'm using a site which covers multiple related games and there are topics
that have the same name for each game. These topics are then gathered into
hierarchies of MediaWiki categories. Is there any way to use some kind of
namespace mechanism to allow the same category name to be used for multiple
games? For example, given the game prefix names WoW and WCIII, could I have
WoW:Categories and WCIII:Categories?
