Have you looked to see if it appears in your discussions you can chose replied to or posted.
I also submitted a post about accepting card payments a while back that got no replies, it did "go live" but I have to assume no one had any knowledge that would make things clearer for me.
I was asking a specific question about the New attachments for smart phones that mean you can swipe someone's card when not in a shop situation. I work on foires and markets so the idea bears investigating for me. It seems I am ahead of the game and no one else has heard of or uses that gadget yet. Hey ho.
