A wiki is a good idea, and this is quite a good place to gather information. However, I think that a separate wiki website (i.e. a Fandom wiki) would be better for new users to find information.
If I was a new player of this large game and not in the Discord, I might google for ‘sector’s edge wiki’. If I received a link to the forum as a search result, I wouldn’t think it was correct and not click on it.
If the game gets a lot more players, the number of players outside the Discord server will increase. So will the number of people who won’t click on forum links when they’re looking for game wikis. This Wiki category is good for pooling our information, but I recommend that the information goes onto some sort of website as well.
This could work by having a Fandom or other MediaWiki-powered Wiki (that could be self hosted as well). Otherwise, the wiki could be a non-editable site (a sub site of sectorsedge.com) where information is migrated to from here, once it has been read through. The second way is also a good way to filter out spam.
This is just an idea. We don’t have to take it in full or in part, but we should consider it.
