That makes sense, and I don't think it is just you. FWIW, we opted to purchase RafflePress to run the giveaway - which along with some nice features including random winner selection comes formal stuff like the rules in a legal template and a structure that is not very customizable and I suspect was more of a deterrent than a reassurance.
I regret that the tone was so far off from what it should have been - this was just me and my family doing a "first" for us. There is certainly a lot we are going to take away and learn from.
