Ricardo:
Your tracks are nice.
But remember some things:
Your files are always over 6 mb....and they are not so quick to download for all people. Now,If You want also to update tracks for tests...well, i think a lot of people will give up on downloading these version of tracks.
Furthermore, until will not be available a real track editor, Your tracks are only a "graphic" update...and when You got the race version of a track, probably You have no interest in using another similar, without sponsor.
But this is only my opinion....Regards.
