181411 Mod rewrite expert needed!!

I'm using the code in the attached file to create "fake subdomains", but I need some changes made.. I want to have subdomains such as.. [login to view URL] So.... [login to view URL] [login to view URL] would still act normally.... but any subdomans including ones with "www." in front of the username would follow the same rules as ones with just the username; only exception being that.. [login to view URL] [login to view URL] ..would redirect to the same place ([login to view URL]) & the one with the "www." at the start wouldn't redirect to [login to view URL] I also want to make a couple of small other changes - it would also help if you're knowledgeable in PHP. If you're going to make a bid please mention if you have instant messenger software & when you'll be able to do the job.
