All you have to do to edit any page is go to that page and click on the 'edit' link near the top of the page. (See it up there?) Then you'll see the raw text of the page and you can change it and save. Fun!
If you get a login id (upper left hand corner) then you can make a stable userpage and get to know us. We're very friendly and we can help you with editing.
