Thanks MoikMellah!

I figured as much.  At least knowing about this in advance, it could be possible to keep record on your own.  If your game ever starts making serious money (not likely for me I think!) you could worry about checking the licensing on your art, or have a minon do that (bwhaahahaha!).

Still it would be nice if they did track your username as you downloaded and fire off an email if something you downloaded was "de-listed".
