I've got kind of an interesting question as both an artist and as a commissioner. When at a convention and commissioning an artist - how do terms of service work? I know as an artist myself I've never thought to take my own TOS along, but I've never had anyone ask for it either. I would assume when a commissioner commissions an artist at a con they are still agreeing with their TOS, same as if they'd done it online but not bothered to read it. But then as an artist should you have one on hand or on your table for people to agree to?
Just a thought I had tonight while working on con commissions. For all those commissioners know I could have a TOS that says I keep all art, original or not, and they agree for me to use it as a dart board.
