It is just an idea I got today, but I have seen on some dating sites if a person can't afford to purchase the ability to communicate, someone else can pay for it for them kind of like a gift so they can communicate. I can't afford to purchase anymore credits myself, but a woman I am communicating with expressed interest in buying credits for me so we can stay in contact until we meet. It could be a very profitable idea to make it possible for people tp be able to purchase credits for someone through gifts and flowers. You could create multiple sizes for people to choose from.
