The "Item List" section is reserved for the data actually extracted from the search.xml file (you should read the Item List page for more detail, did you click on the link?). What I mean is, it's not for randomly add things in without proof.
If you want to contribute, you need to do the following things (I'm just summarizing)
Extract the search.xml file from whatever version of the game you're using. Upload it somewhere.
Find the Item List that contain the gun in that list.
Add that Item List in the Item List page (following the page's formatting), and include the link to the uploaded search.xml file for reference (there are already 3 files there for pre-YOSE version of SoD, Breakdown and Lifeline uploaded on mediafire). Also you need to note which version of the game the file is from.
I thought lately that the characters pages (both playable and non-playable) could benefit if they would be categorized with their respective skills (ignoring the "basic" ones, obviously), which will result in a "Character with Medicine Skill" "Character with Literature Skill" or something in that manner.
I think that the efficiency of browsing through characters would increase, and it would be easier to find characters if browsing through their respective skills, if that would happen, so what do you think about it? I would not do anything on that subject unless given the permission from you, as it is seems to be quite a big step.
Why did you undo my(not logged in) edit on black fever? Where does it say that Thomas Horn had it? He was bitten and thought he was in a different zombie genre. Its confirmed in game by the number of people that survive zombie bites without getting it that you don't get it from just a bite. So justify to me why he belongs on the list of confirmed cases when he was not a confirmed case and I will drop it.
I found a new Potential homesite that is not listed on this wiki. It is beside the Supermarket in Marshall. I think it is called "The Almo" It's like the Church of Asension might want to make an article about it. Thanks.
