Forum:New to the Wikia, What can I do to help?

I just joined the Call of Duty Wikia, and was wondering what I could do to help around the website. It would appear as if the damage values presented on some of the guns for Black Ops are incorrect, perhaps I could help with that? According to Den Kirson, these are the weapon values for the weapons, would it help if I were to fix everything according to these? Also, when I edit an article, do I simply need to source my findings by posting a website? Brand new to the wikia scene, but I feel that I could really help out and benefit the website.
