Howdy. I am new (obviously). I received this post via Google Alerts, and decided to take a look at what you were discussing.
Before posting further, I want to make full disclosure that I work for a main competitor of Calling Cards dot com (SpeedyPin dot com). However, I want to tell you that they are indeed a good business that has been around for many years.
Yeah, I know you don't see too many competitors saying good things about one another, but those of us in the prepaid phone card niche that run honest companies, and provide our customers and affiliates with good products, are few and far between. Thus, I feel it's ok to speak up when a good company is asked about.
I hope I haven't broken any of your forum rules with this post. I just thought you'd want to hear the truth from a source "in the know."
