What is M-Color? - Where does this category comes from?

Who decides which categories are needed? We should introduce 3-4 metadata for defining the forum tree, perhaps: Topic class (Best practice, development, Configuration, End user problem, Feature suggestion, ...), M-Files component / add-on (M-Files Admin, New Web Client, Process Maps, ...), language: ALL or 1-n specified languages (interesting e.g. for DACH region), perhaps also Branch (Finance, Lawyer, Trade, Public Sector, ..., private user's small version(?))
