Seems neat, but some screenshots or a demo account would be nice so I can see the product before I give away my email.
I understand if you meant to have it in the landing page, which I will get on it, I'm planning to have a demo account setup by end of this week.
As for the pricing, I really haven't decided on one and when to charge. But rest assured, I've always planned to grandfather users who signed up before any payment plan is launched. Basically, anything you use for free when you signup will forever be free.
