You can also possibly install a discourse client (mobile app). Currently as I see it, only discourse is FOSS and has a decent UI for modern user’s expectations.
Anything less than this would certainly exclude most non-technical users. That’s how things have been before discourse came along where only mailinglists were available. My hope is that now a there is a lower barrier to entry for new users, even if that’s at the cost of running JS (if one is not willing to use it via mailinglist mode).
