Moe I have gone back and tried to help past posters. Most of these questionsI do not have the knowledge to answer.
The other part, is not to be the only poster here, others should have the oppertunity to pipe in

I've gotten pretty good at "answering" posts by asking more questions, but I can't do anything with those! Sorry.
