I have no idea about the user system.
@realZ Not entirely sure on your question, but you could try here
Link the theme into node_modules with npm link and then use grunt to watch changes and rebuild automatically.
@frissdiegurke is correct, we've moved the list of plugin hooks to the wiki.
It needs a bit of standardisation, since new hook documentation was added rather haphazardly, but most (if not all) of the hooks should be there. If not, they can be added by anybody who wants to, by editing the wiki doc itself.
@julian Thanks for the update 🙂
Heroku allows developers to run small instances for free (even their redis add-on is free), but if your site becomes popular, you will have to pay.
We have a guide to setting up NodeBB on Heroku in our wiki.
Yup. Check this out. It takes a hell of a lot of time to get used to but with some practice you'll find yourself writing 20 lines of html code in half a second, I'm totally serious.
