Wiki 10/16/07

When looking on the Wiki's site I found that there are people called administers that overlook the site for any false information and/or things that just shouldn't be on there. These people have special rights to the site that no one else has. I think that their are more than just a few people who have these rights too because without many people it would take someone forever to look through all of the information that Wiki provides. My question is are these administers make money off the site?
