Grow posted a fantastic series/compilation of SFOR-related links on 2/4/19 starting with post# 47914. There are about 5 or 6 posts in a row that are completely filled with links that will have you reading for days. Make some coffee or popcorn... lots for you to catch up on!

Also, when viewed on a computer (versus the phone app), you'll see a series of "stickies" that will akways appear at the top if the message board. Check those out.
