Which wiki is being officially supported?
I’m looking to contribute, please reach out with any information on the wiki team.
and where is that wiki ?
it is currently unlisted, because we are still working on it. it has very little information so far. But once we have some more information on it, we will list it 
Are you taking volunteers to help with contributions?
sure, the wiki post is limited tho. we have edit permissions for regulars and mods and admins. but we will also link a google doc where you can share input if you are not (yet) a regular.
we are currently testing a few things, tables, links, etc. once that is done we will list the topic.
Where could I find that google doc? Or if you could DM how to get in contact, that would also work!
not sure if @BowUser already has a google doc? if not i will create one later. it will also be linked in the wiki post.
I listed the Wiki. You can find it here: The Official Wicked Wiki
Its a work in progress and far from being complete.
