The run of show is intuitive and clean. I ran into my first pain point because I only uploaded 3 or 4 contacts to test the features. I did not want to throw my whole contact list at them without knowing if it worked. The problem was when I attempted to add the remaining numbers in my contact list to the previous 3 or 4. It is not yet possible.

A simple email and the team responded saying that they are working on it. I can rock with that.
