Hey Paul, I just want to start off by saying thanks for your past help on the support pages, and thanks for such a wonderful plugin. Achievements for WordPress is easily the best and most fun achievement-creating plugin out there for WordPress users.
Secondly, I just wanted to put out a request for a future update: Please, please add support for BuddyPress media.
It would be awesome to let people unlock achievements by uploading different kinds of media, and/or varying amounts of said media.
I know this would be something down the road for "Achievements",
if added to the roadmap at all, but I just wanted to put my opinion out there.
