This is so cool--thanks for building something that has the potential to really help people. Is there some sort of vetting process in place for the TextAngels who sign up?

There doesn't appear to be any. I clicked to sign in with FB and after granting the webapp permission it presented me with three different users. It gives the city and a unique id for each one. Each has it's own threaded conversation and reply to whichever one you want. I like the idea but not sure about the implied safety of it for those in need or vulnerable....

This was built during Twilio's hackathon. It was built and live within 5 hours. Not sure if there's a whole lot in the way of infrastructure built out. However, it's a great start!

Additionally, it gives you the option to call them without any clear indication that they have control over the action.
