Forum:I Need Help with the Bejeweled Wiki

Hello! I was wondering if anyone here could help me with a sight problem.

I recently become a member of the Bejeweled Wiki, a Wikia dedicated to the popular puzzle video game franchise. While I was searching through the Wikia, I noticed that there are a lot of irrelevant articles and unnecessary images. I looked to see if there were any other members of the Wikia, and to my surprise, it seems that all of the other members have left. Even the creator of the Wikia appears to have disappeared as well. After looking through the Wikia, I decided to create my first ever article, titled Challenge Mode. I have been spending the past few days contributing to my article, and I think it’s coming along quite nicely. So far, I’m having fun improving my article, and I plan to create more articles for the Bejeweled Wiki in the future.

My question that I want to ask you all is how do you delete images and articles from a Wikia? Do I need to be an administrator to do that? If so, how do you become an administrator? I would really like to tidy up the Bejeweled Wiki and try to make it popular, because I think it’s somewhat depressing seeing a run-down Wikia dedicated to a popular video game franchise.

I would appreciate it if anyone could reply to this and help me overcome is obstacle.
