No one knows everything, but if I know a little more than you, I'll be glad to help. And if you know more than me, I'll learn.
You can reach me at [myusername]@yahoo.com, but please, if it's about a question or one of my comments, post here in EE.
These days, my day job is keeping me busy, so if I don't respond right away, don't think I'm ignoring you. I will pop in and respond when I get a chance.
