I've recreated a Linguistics community here in mander.xyz. As the sidebar says, it's for everyone, regardless of previous knowledge over the field, so even if you're a layperson feel free to drop by.
Wait -- now it takes me direct to the mander server. Before, the one that was in the Lemmy bullet point was perfect (whatever it was would go to /[email protected] which would work on any kbin/mbin server whether the community was already federated or not).
Edit: Actually, I don't know if that's ideal, because bots will hit the link and cause federation load which maybe isn't ideal. But, it was convenient 🙂)
