thank you Lauda, much appreciated

Your signed message does verify, but it's useless to me. I was wrong about my previous statement, but that's why I triple check users before I add them to anything.
You did not use that address to invest with. You used: 1569sNNM8G6jhAqiMaoReEnfc146q3LAQj ;; that's the address that you have to sign a message with.
Hopefully first repayments will happen today. I may extend the claiming period for a few more days, but after this no further claims will be accepted. As an investor you need to act responsibly in time.
thanks for the extension, glad i logged back in to check
