Just subscribe to ReformedWiki2.0 and watch all the videos until the end—that's all :). That's how we get the YouTube algorithm to push the videos out to more people!
There are several ways you can give. My expenses are currently about $1,000 each month (video voiceovers, hosting, etc.). I'm happy to pay this myself, but if you want to join me in this journey, that would be great!
