It's been a long, iterative development process. I started back in April 2013, had the first go live in January 2016. Since then its been iterating and improving the software, getting feedback and making updates as I go. I'm a bit limited in how much time I get to spend on it due to having a full-time job. Getting more content is at the top of my list ( https://sgef.cc/wanthelp ). I really want to show what Sagefy -- and these learning ideas -- can do :)
Thanks again, cheers!
