What I have done so far...
My Contributions
Updating Outdated images to current
I have been carefully uploading new updated versions of the pictures on the wiki you will currently see in game, and will continue to do so, until roughly 25% of outdated images are complete, it is a big task so I don't expect all of it to be done soon.
Fixing up pages with Vandalism
I am making sure that vandals work gets deleted and the user banned from the wiki, I help this happen by putting {delete} tags on vandals pages by seeing recent changes to the wiki and if they are not positive, and don't contribute in a meaningful way I put the tag on and report the user for violation of the Wiki.
Fixing up outdated information on pages
As you have probably seen already I have updated Vatel's image and plan to completely fix all outdated information on that page for both players old and new so that you can see all of the items he has, including gunner stuff.
Miscelanious
Any other project I am working on is probably in the things to do page on the Wiki.
