Quick update: I might actually swap over to Continuwuity, since I heard that the Tuwunel developer isn't the kindest person: https://forgejo.ellis.link/continuwuation/continuwuity/issues/849#issuecomment-16130

In the time since, however, Jason has made threats against multiple members of our team, so I can't foresee any active collaboration.

Shame, since the server works (although Continuwuity might be better set up for Element Call as well)

It seems to work well from what I've seen, but I mostly use cinny! I've been trying out element X, fluffychat, cinny, and commet-- I just like cinny the most, since it seems to work best with the spaces.

Cinny is great as long as you don't need any voice chats, although that will be added in very soon (along with threads, better grouping of subspaces, etc). There are open pull requests that just need to be reviewed and merged in, and there are links in its github to preview the features of the PRs.
