YES! Listen up backers :) If you get an email to your Kickstarter account from "Rob" in response to a new backing or a pledge change.... well you are talking to the real Rob.
Here's the deal, I email everyone when they back this project. I try to reach out to you and make a connection because I'm excited that you joined us here. Have you ever seen one of my videos? I get really pumped up when someone backs this project that I don't know what to do with myself. SOOO..... I email you.
Best thing you can do is write back. You never know what might happen.
