Ranbrew, David usually checks on the forum a couple of times a day unless he's busy. So he must be busy today. However, I'm sure he would be willing to talk with your son. I will e-mail him and alert him to your post.
Thanks for answering, David. Is that your laptop or desktop e-mail that is messed up? Or both?
Ranbrew, you can e-mail me for David's number. It's in my profile.
