I wonder if it's possible to create a Lemmy community that behaves like a PhpBB forum, that is, threads are supposed to be long-lived, so they are not sorted by age, comments are supposed to be single topic, so they are not sorted by thread, and you can jump right into the last thing you saw.

It looks like a great experience to after you publish something, you just go and create a Lemmy instance (with closed down registration) to host QA forums, news discussion, and just community meetings. It looks much simpler and straight forward than managing it with all of twitter, reddit, and facebook.
