Hi Benberg:

The user finally did respond and said he had sent me a PM. I never received any such message, and so I requested that he have an admin let me know that a message had been sent. That was over as week ago and I have not heard back.

I definitely was not seeking anything in exchange: just passing along a coupon to help out a fellow traveler. As I mentioned earlier in the thread, I had only wanted to hear whether it had worked.
