The craigslist app is great, but when purchasing something it almost always take 3-4 emails to agree on a place and time to meet.

"CraigMeet" could offer the ability for buyers and sellers to drop pins, add meetings to calendars, and maybe even allow location sharing (like Uber) when authorized by the user. Meetings would be much easier to arrange and it might even be possible to leave feedback as well.

I would be more than happy to help test out these features.
