I think its a great idea, the wiki needs some love for sure, it would help new and old players alike. I have no knowledge in wiki editing and as a newer player i don't have access to many items but I am all for revamping the wiki.

I would think that maybe some guides could help you with items and stuff for your screenshots if you were to ask them as it takes some of the load off of them answering questions when players could just look it up on the wiki for themselves.
