I need to reset stats before a party.

[Mordigant]

Where is the reset button?  I recall there was one when I last had to do this but I forgot where it is and can't seem to find it.

Hm... Not sure about a reset button, but you can delete the "ultrastar.db" file in the preferences directory (~/.ultrastardx, %appdata%\ultrastardx...) to clear all stats.
