Thanks for all the great suggestions! I'm going to investigate them and hopefully add them to my list of ones to participate in. I created a spreadsheet that I'm gong to use to track how much I get each month for each one of them. It had never occurred to me to use sites like this as a side gig to make a decent little additional income, but now that I know I can't imagine why I wouldn't do it. They take very little time and I have both my current and my old cell phones running videos while I'm at work during the day. I'm going to start tracking in April. Can't wait to see how much I get altogether!
And if you think of any more...keep 'em coming!
