We have met before on the Community Central Chat, and you've said you need some help with the Wikia. I'm offering myself to do so. I can add some information about the historical info of the tanks, as I'm working at a WW2 museum. But for the rest, I can almost do anything.
We're currently in dire need of accurate historic information on each and every tank that you can provide. If you can provide I-R-L pictures of tanks, we need them too. Check the forums for basic formatting rules, or check out pages like Renault Otsu. Thanks!!
