Heaven forbid that one should be courteous to one's Customers.

It isn't an issue of politeness. There is an established product compliance and support system provided for DAZ3D product to purchasers that free's creatives up to focus on what they do best 'create' and gives customers a standardised accountable problem troubleshooting method. Which is actually more of an asset to customer's than a slight by the vendor. The support system even goes as far as a 30 day money back guarantee which is pretty much unheard of in this industry. When I was vendor here at Rendo, I had customer support occasions where I went through pages of mail correspondence because a customer was not familiar with installing from a zip file. I mean literally pages of writing and screen captures showing the process. After a week of no success to this fairly straight forward procedure I suggested I just refund his purchase and lose $3.50 my share of the ticket price. We agreed that was mutually equitable at that point. I guess I must of worked for 4-5 hrs for that $3.50 refund...
