School context

A school example. Pair with social media in schools: pupils are not a public Reddit audience; staff must moderate today; no ads.

A class of ~25 plus one teacher currently pastes article links into WhatsApp and maybe a Discord “homework” channel. They need threads and a class-only board, not another chat app (messaging).

Hour one (school-run Lemmy)

Run Lemmy for the school (self-host). lemmy.hacktivism.ch shows that self-hosting is possible; it is not a pupil enrolment instance.

Step In school vs Reddit / WhatsApp
1 Staff create school accounts No Meta/Reddit SSO, no phone number
2 Community !class9a@school.example, federation off or allow-list only Subreddit is public-by-default and owned by Reddit
3 Link + short body for the week’s texts WhatsApp scroll, no thread
4 Teacher + one pupil as mods Distant platform queue
5 Optional parent read-only Mixed family WhatsApp

Config pointers: generic join-lemmy.org; example host README.

Policy, not just software

Do not federate a class community to the open Fediverse unless the school’s legal/staff policy says so. Minors, consent, and closed classes come first (Saura et al. 2026 on the schools page).

If the school later changes host, !class9a@new.example is an exit Reddit does not offer.
