I've made a subscription request (apparently that's a thing on some communities? no idea why that'd be required here though) to this community, and it's still pending after a while. I think it's dependant on the mod being active to accept the subscription requests.
edit: If anyone makes another community, please do post about it here, though. I don't really have the bandwidth to moderate an SC community, but maybe someone out there will want to pick up the slack.
