Thanks for the feedback! It's definitely early and we definitely plan on expanding to cover more types of trips, like road trips and bachelor parties and vacations, but for beta we wanted to keep it simple and stick to camping. I eventually want to make it like a group tripit, tracking flights, hotels, and rental cars, etc (not to mention make it more user friendly than tripit)

All your bullet points have been added to our backlog. Eventually I'll add a mobile app which will definitely include a packing list.

Integrating with Facebook and Dropbox and other storage providers is also on our list.

I figured the Discussion box was a good enough "scratch space" for trip members to discuss ideas for things to do, then when you decide on an activity, you could formally add it in the Schedule tab.

Thanks again for the feedback!
