Mardoch
Defender of the Universe
I've been coming since IX, which makes 7. Next year will put me at 50% of ProgPowers attended. I've known about the fest since 6, but IE with Barlow and having a job meant 9 was the first I could get to.
This year makes 11 straight ProgPowers for me, Gold Badge for the last 8 years. My husband, VenomGa, has a year on me with 12!
Just 3.5 for me, scattered throughout the years: #6, 8, 13 and just the Wednesday event this year (I'm counting that as a partial).
