I signed up w/ my github creds and made a small "hello world" GET endpoint. Here's my comments & questions so far:

1) allow non-json responses 2) why would I do pass-thru? for metrics? 3) add test data generation features for mock responses 4) add at least limited scripting features for both pass-thru and mock

Looks like a good start to me and I was not particularly bothered by the current sign up.
