Me and EdB have been loving this idea for a while now.
It will be 3 days where everyone in the b2evo community jumps on board, and gets involved.
So people who can develop will be developing.
Other people can exchange thoughts, ideas, support with each other, or submit ideas questions to the devs. OR HOPEFULLY when you learn something, update the WIKI with what you have learnt!
It is a way to get a huge active involvement in a short time, so a lot of stuff can happen in a short time.
So by the end of it, lots of users will have a better knowledge of how to use b2evo, the wiki will be updated to satisfy everyone, and devs will of made great stuff, and got a lot of feedback on what the users want!
So yeah... Anyone who likes the idea posts here, and the best time for the hackathon to be held for you.
For me, anytime after the next month I am good.
