Welcome to the Call of Duty Wiki, Scaryhead! Here's some Editing 101 on how you can help:
Recent changes is a great first stop, because you can see what other people are editing right this minute, and where you can help.
Read our policies, if you haven't already. You'll be informed on the do's and do not's, as well as some guidelines when creating new articles.
The Sandbox is a great place to test things out if this is your first time editing wikis. It is advisable to know what is commonplace on the wiki, such as templates and categories, and how to use them.
Questions? You can ask at the Help desk, the "discussion" page associated with each article, or browse through the help directory. Feel free as well to ask on my talk page; we're always ready to help recruit.
Have feedback? The War Room is used to discuss changes to wiki or other community related issues. You'll need 50 main space edits to vote, recruit, but your opinion is still appreciated!
I hope you enjoy editing on the wiki recruit! Ramirez, this is Foley, we're Oscar Mike!
