Does anyone have an experience with AWEBER like service but.... that offer an API to add and remove subscribers.

AWEBER is great but I find myself time after time struggle implementing aweber service within my systems just because there isn't a way to automate some of the actions via API.

I talked with AWEBER more than once about it but I have the feeling that we are not going to hear some news about it in the near future.

Anyone else found the need for an API?

Dont get me wrong, I think that AWEBER has a great service. But they can do better.
