At http://supertuxkart.svn.sourceforge.net/viewvc/supertuxkart/ there seems to be two options for which version of STK. There is main which seems to lead to the current EXPORTED version of STK. Then there is media which has an older version but with none exported files. Is it supposed to be this way, and if so which should I use (I want to get the latest stuff but be able to edit it).

It seems like you don't quite grasp the concept. As you say, there is main (in which you probably want the latest working copy, which is called trunk), and then there is media (and as you can see, the same principle with trunk is here as well).

Hmm... downloading Elephpant from trunk when he already has a trunk... not to toot my own trunk, but I smell trunkception!
