I’ve been collecting my own database of paying markets for quite some time now because I felt like there wasn’t a large enough database for me to sift through every day.
After I created it I thought about opening it up to the public. I thought hard about opening it up for free. I then decided that it was too much work to maintain for me to do that without some sort of payment.
In the end, I decided to offer a subscription model with a free trial offer.
Plus, it gives me a chance to figure out how PayPal subscriptions work.
