If anyone is kind enough to help I could use some QL data. I used to have EddyBo help me but he's no longer with us.
Please PM me and I will reply back with the particulars of what I'm working with.
Many thanks.

Post what you want here.
If someone want's to help, we'll help. But if you want some help, you need it make it easy for the person you are asking, or already have an established relationship with them.
You didn't use logic or reason to get into this opinion, I cannot use logic or reason to get you out of it.
You cannot over estimate the unimportance of nearly everything. John Maxwell
