I'm no mod, but based on many other mods and extensions for games on SRC, the main SRC page is for the vanilla game speedrunning.
Mods and extensions usually get their own page under the name format "(GAME) CE", ce for category extensions. As far as I see it personally, MTM2 speedrunning isn't popular enough to warrant its own ce page, and for SRC culture, I don't see it fitting into the main page either. I'm not mod, not making any decisions or anything, just stating how things normally work with that.
Not much left to say about that, but yeah, this is just for the vanilla game. Maybe in the future we'll have category extensions but not for a long time. Currently we only have 2 active players and we definitely need more to even consider adding other things because it works well as it is now.
