Basically, in regards to adding a FAQ or other content to the wiki, the "policy" (such as it is) is to have the information be as accurate and up to date as possible. As far as formatting, we prefer that it be similar in design to what is currently there but we are pretty open about that. If you have a design that looks good on your wiki info, feel free to use it, creativity is key on this stuff I am finding. We have a FAQ for the wiki at the following link as well for folks who are interested: http://wow.allakhazam.com/wiki/Frequently_Asked_Questions
In addition, you can use the formatting from any of our pages in creating your own. However, if you use any sources outside of Alla's, please make sure you give credit at the bottom of the page you work on to that site you get additional info from.
Also, if you like, here is our main wiki portal so far: http://wow.allakhazam.com/wiki/
We have tons of redlinks and guides that could use some love so if you feel froggy, by all means help yourself :) The wiki is open to any and all who want to work in it, it's your community so the wiki simply makes your community here stronger depending on how much or how little you want to work on that. It isn't mandatory by any means. Think of it as Allakhazam's version of wowwiki.
