Nope, no sponsored ads, and we're trying to keep things simple. The API is part of our long term plans, we're not currently developing it though.
You mentioned using similar services before, any positive/negative thoughts on what made you a happy/not so happy customer?
And just...thank you. For your feedback so far, it really made a difference :)
Yes, it is; statistics project a 10% growth rate/year for FoIp market (by 2017), so I guess we could say that it will adjust, not disappear.
Thank you, likewise :)
