Per some recent discussion, artist batting averages are now based on their TOP THREE submissions. This means your bad submissions won't hurt you, as long as you have submitted good ones!
Artists no longer have to remove old submissions to improve their average, they simply have to submit new, better games and movies! Artists are also now free to submit goofy stuff that may have previously hurt their average.
Everyone should take a moment and thank Liljim for implementing all these great changes! James does all the PHP / database programming, so without him, these features wouldn't happen.
