not much a fan of Discourse - especially the continuous scrolling. But use to it due to Letsencrypt forums using Discourse - probably Caddy and Letsencrypt forums are the only 2 Discourse forums I frequent these days - probably for the subject matter more than choice of forum software
still better than some other folks choices of using the old mailing list or google groups !
personally, I used vBulletin (as I worked for them for over a decade mainly help forum owners optimise their server setups for performance and scalability pre-vB 5.x heh) but now use Xenforo (https://community.centminmod.com). Wouldn’t mind seeing Caddy forums on Xenforo one day
i’ve tried nodebb and i preferred it over discourse - at the time i was playing with Ghost node.js blog so loved their integration in nodebb
