I am excited to announce that I have just finished deploying a new wiki service tied to lemmy.dbzer0.com.
https://wiki.dbzer0.com (Ignore the certificate errors for now, it some leftovers from the downtime yesterday. Will be fixed soon)
The most cool part of this setup, is that while anyone can read, only users who have an account in lemmy.dbzer0.com can edit. This should nicely prevent spammers from causing issues, and can help us tie edits to accounts here. if your account gets banned in lemmy.dbzer0.com, you also lose access to edit the wiki as well!
To manage that, you simply need to register an account on the wiki, then write that account on your bio here. The frontpage of the wiki provides the relevant instructions.
So if you needed a place to add official pages about your community with info, now you have the place!
