End of Trial: Free Curve Black or Curve Black Legacy

I would like to make a suggestion. I am a very early Curve Black Legacy customer. I have used Curve on and off as many issues just made the service too cumbersome. However I have started using it more as things seem better in many areas. Ideally I would have liked to have been in a position to meet the requirements for Free Curve Black, but at the time I was not able too. My suggestion is that Curve should just allow Curve Black Legacy users to get Curve Black Free after referring 5 users as an open ended offer. I am sure the average Curve Black Legacy customer will not cost Curve anything more after such a switch. The promise made when we bought the cards in the early days is that we would get Curve Black for life. This would be a good compromise and might get those like me to switch. Maintaining a legacy product for a small number of customers cannot be very efficient either.
