Greetings from SOG, recruit. We're happy to have you aboard at the Call of Duty Wiki, so here's a briefing on how you can help:
Our policies are something you should get familiar with, so you can have a good understanding of our rules. You will find very helpful information on what is and is not allowed on the wiki.
Recent changes is a great second stop for beginners, because you can see what pages other people people are interested in, and which ones might need your talents! Also check out the Community Portal for a links to other useful pages!
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.
Have questions? You can ask at the Help desk, or post a message on my talk page! Also feel free to contact an administrator; sysops' names are highlighted in green and bureaucrats' names are highlighted in cyan. But remember, my friend, we are all in this fight together, so feel free to ask anyone you like - we are always watching each other's backs!
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 look forward to having you here, my friend! It is always good to have another soldier on the front lines of editing!
