Awesome plugin! We use it on our buddypress gaming site and it goes a treat. Bit of issues moving from 2 -> 3 though. Is there a way that I can change it from showing the user achievements at:
domain.com/author/[username] --> domain.com/member/[username]
it's would just be easier to have it this way for buddypress integration. Also is there a shortcode for how many karma a user has?
Love your work.
