We are gauging interest in another Haskell hackathon to be hosted at U Penn in May, the weekend of either May 15 or May 22. If you might be interested in attending such a thing, send me an email (please DON'T reply to all!) with your name and whether you have a strong preference for one or the other weekend. Feel free to respond even if you are not sure; will be a separate official registration procedure once details have been nailed down. -Brent
