@passive420 I sent you money some time ago for boards and I never received them. You also stopped replying to my DM's asking about them some weeks ago. What is going on? I'd like the boards or a refund please.
Yup, I've purchased a couple of things from him over the last 6 months and had no problems.I’m sure Richard will resurface. He’s a good guy.
All good now folks, many thanks for the support here, Greg, Roar and Steven, diamonds all of you.
Had an infection from operation, got very poorly and it knocked me sideways for a bit. Kind of a depression, couldn't look at the computer, just read books.
Chris has been made good, we are friends. My shameful lack of response is not my way. Apologies Chis, second package on it's way.
