Add an additional tab onto beyondcanon.com's navigation bar- maybe called something like "COMMUNITY", "DISCUSS" , or "FANDOM", with links to popular community-run discussion forums/sites (omegaupdate, r/homestuck, r/homestuck discord, mspfa, etc.) This would probably need to be with a disclaimer stating that beyondcanon does not officually endorse/or is affiliated with these locations and that they are at your own risk of enagagement.

This would in theory help recapture some of Homestuck's original appeal- the tight integration with a forum to discuss it helped spark fandom engagement- whilst avoiding the need to actually host and manage these spaces, since fans have taken up that role instead. Also would help new readers grow more easily engrossed into the community and thus be more engaged.

(Might've already suggested this, but I didn't see it so maybe not. Apologies if so.)
