Wiki MVP - There would need to be a restriction on how many times one could compete. My idea is, if you end up in the top three then you can't enter in any more MVPs until the next year. This would keep it fair and easy for new members to come in and contribute and actually stand a chance.
Pro Wiki Submitter - With that, there should be a certain bench mark, say like 50 or 100 (maybe i'm a bit high) Wiki pages edited or added on. The 10,000 points seems like a bit much, but if everyone else agrees than I will also.
Staff Promotion - That one is a problem. There isn't enough activity to warrant more staff. As well as that, there are some people who would be active only to be on staff, not to actually help the site, and besides that there really isn't a way to apply for staff. If we could get more members here and have the place more active then that would be a good idea. But contributing to the site isn't the same as being active in a forum, or forums, so I don't really think this one would apply here.
Wiki Experts - I don't have any issues with this one. Seems like a good idea and it could be implemented just like with the video game pages.
