Not sure if my VIP expired or not, but my name is white, I have the sponsor banner under my name, I cant upload maps, and i can still change maps on the server.
IIRC go here: http://forums.tf2maps.net/payments.php and it should show you if you have a VIP subscription left and what date it runs out on Someone else who has VIP should probably confirm this
Mine expired a few days ago and as you can see, the result is the same. Don't really see any problem with it, though.
