I recently wrote a blog post about modern forum software and NodeBB was one of the many. Check it out here and let me know if I need to delete things, add more stuff in, or modify it. Thanks
Great 
Just a few notes:
This software is powered by Node.js and built on Redis database. When installed, NodeBB will have two default themes, Bootstrap and Lavender.
It also supports MongoDB and LevelDB out of the box.
The theme is called "Vanilla", it bases on Bootstrap (as does Lavender) and is skinable (e.g. with Bootswatch skins).
Add contents to Sidebar
I'd mention sth. like "widget system" since whether it's a sidebar or whatever depends on the theme but ok.
You could add the fact that NodeBB uses Markdown as preferred post-syntax, I don't know about the syntax-usage of the others but it may be worth researching 
Oooh, Legion... best keep an eye out for them, would love to chat with their founding team, as we seem to share a lot of the same goals.
Best all be friends, no? 
@frissdiegurke Thank you. I just fixed the post. @julian I did the same thing too 
@Tan-Nguyen should write about the widgets system of nodeBB. Some kind of the most different thing I have seen in a forum system.
I'm sure @psychobunny would love that. It was his idea entirely
