Forum:Hey where can i find some editors for my wiki

Hey i have been working on a bunch of wikis that i think could really use some improvement. I need to know how to add the category things on the left side. Also i want to know how to make the background of the whole wiki change. Specifically speaking i am talking about wikis that involve bands and Darkness wiki and Singularity wiki. Please help me out here.
 * What do you mean by "The category things on the left side"? Do you mean the sidebar? If you do, you need to edit MediaWiki:Monaco sidebar (MediaWiki:Sidebar, if you have viewers who use monobook). Random Time  10:18, July 3, 2010 (UTC)
