To answer some questions:
I'm leaving because of a lack of motivation and time. Between work in the summer and college in the fall, winter, and spring, I have little time left for social activities, let alone being a developer. As for what's next for me...well one of the things I pride myself on being is the youngest FH2 developer (as far as I know). At 20 years of age, all I plan to do is enjoy my summer, and then concentrate on school in the fall. I certainly won't have any time to join any new mod teams. I might come back to FH2 at some point, but it'll probably be at least a few years down the road.
And as far as the team goes, we still have plenty of dedicated devs still doing work on the mod. Just less than we might have had compared to previous releases. But that doesn't mean we are struggling to get work done or will stop development next week. As you can see from the last news update, everyone is still going strong.
