I have a suggestion to consider. The main website says, "Test drive NodeBB on our Demo Forum." I think that would be better off being a link like- "Join our Official Community." - or something like that. (Can still be referenced as a Demo elsewhere)
Reason why I think that is- demo forums, to me, usually seem like empty/useless space placed to see what the creation look/feels like. Where this actually has potential beyond that I.E Act like a community of sorts.
I wasn't sure if this was meant to be posted in Feature Request so I just added it here.
Feel free to move it, @psychobunny (If that feature exists o.o)
