D&M,
I really appreciate the reply. Something like Question Time was what I was looking for but couldn't find via Shopify search or Google. The is will be a great app with a few improvements prior to paid release (I sent the Matt, the author, a detailed suggestions list).
I will check out the others as well. I'd forgotten about 5 hour customer support - that may be worth looking into but I don't know if they could handle my products - expensive espresso machines and grinders that get allot of technical questions.
Thanks
Mike
