9 posts in one day, two of which are to the same outside website, and 7 others which could be considered nefs. You had me fooled for a bit, because it looked like you read the threads in which you posted. If I'm wrong, forgive me. And you are certainly welcome to stay. But so many links to your website so soon is often frowned upon.
That said, I will answer your questions.
(1) It sounds expensive, so no, that isn't a good thing. I didn't look at the link, but everything similar is expensive. If it is free, you'll have to do a lot of work to explain the free part to people like me.
(2) There are other solutions (like writing a check will allow you to pay debts and lend money to friends and family), so again I don't see myself using it. Heck, cash can do that.
(3) So I'll save it for an absolute emergency, if even then.
