Thanks David,
I'm not sure how that works, but I will definitely look into it.
How many suppliers have contributed panels?
Is it a panel I order from my supplier and then send to you
to have it analyzed? or are suppliers volunteering panels
to be part of the database?
Well, I GUESS I could go READ about it... sorry.
Jack
