I'm creating small flyers for my business, and I'm thinking of using quotes from my past clients. If I make the quotes from 'First Name, Last Iniital', 'just First Name', or even anonymous, is it ok to not have permission to have them printed? Being that I acquire most of my clients from Facebook, I have a hard time tracking them back down after the occasion.
I use thank you notes all the time without asking permission. I do the first name last initial thing to preserve their privacy though.
