Yay, so happy that you're working on documentation! As I've been learning UNA I've been thinking that this app would be so much more accessible (and get more users!) with better documentation. I have had to simply install it, and keep turning things off and on again, and make a bunch of test profiles and test posts all over the place just to figure out what all the settings do!

Right now I have a deadline by which I need to complete all the basic areas of our UNA site (April 13-14), but when that is complete (and after I take a couple week break lol), if you are interested, I would love to contribute by helping with writing documentation and tutorials. I have a "Guide to UNA" written already that's designed to explain basic concepts to a brand new user with zero technology experience. It's very tailored to our community - and it talks about differences between UNA and Wordpress since we migrated from Wordpress to UNA - but would be easy to adapt!

I can't post links but here's a preview:

I have just gotten our community site to the point where it's ready for people to join, with customized membership levels, and profiles and discussions are fully operational, and I'm really impressed with how tiny the list of CSS code I had to write is so far!
