What other services would people be interested to have available via slrpnk.net?
Keeping in mind that it should not be too resource heavy on the server I was thinking of maybe a Bookstack Wiki for collaborative writing of fiction and non-fiction?
A XMPP chat service would also be easy to add.
Sadly Lemmy currently AFAIK offers no account integration options, so that will make things a bit annoying.
I think I like the idea better to just offer chat rooms on here. Most people (should) have already their XMPP or Matrix account which which they can join such federated XMPP rooms. But we could also provide a simple web-client that can be used without an account.
Email is out of the questions, nearly impossible to host these days due to the excessive spam filtering.
