ACT Running From Plack
I'm proud to announce that our dev team has officially gotten ACT (the conference registration system used by YAPC) running on Plack. Check out the github repo. We still have more work yet to do. There's still one test not passing, and lots of features to add, but you can start it with plackup, register, login, change your profile, change your password, etc.
If ever you wished ACT had a feature you thought it was missing, it just became a lot easier to add.
