@Tosh I have it on a Single WP, with all the code in bp-custom.php (as at some point I wanted to have an admin tool that allowed changing point values for each item). Site is http://www.suckitupprincess.net
I also have the Malleable them in use, and wp-fp-connect… It is my hobby site, and one day I will put it in action. Work keeps me busy though
