I'm assuming you only speak English, but if my hunch is correct, why would you need to know about other "textboards"? None of the newer ones you wouldn't know about look any different from each other, and they're all knocking on deaths door since the brats that own them can't afford hosting with their puny allowance. BBS are used correctly only by non-English speakers. English VIPPER boards are niche as is, and the neocities browsing, matrix using hipster weeaboo kids that host cheap knockoffs don't have a single working funny bone in their body, so their DQN clones suck.
