Thank you on so much for the well wishes and coming back to find me. Also let me say that I hope exams were successful for you as well. I think each of owe a debt to one another when we join, that being helping new members kind of "learn the ropes", I do what I can when I can. I will look at your post so thanks for alerting me to it.
The two way street analogy I use is pretty simple and it looks like you grasped that part real well. Let me know if I can help you in any way.
