I just set-up a test forum up after discovering NodeBB the other day. It was an easy install with SmartOS. What a perfect marriage together with my Ghost and SmartOS setup! This has great potential and I can, finally, say goodbye to bloated LAMP set-ups .
I've been through several forum solutions with Xenforo as the most recent one. I will start to develop sites using NodeBB from now on.
Way to go guys. Now, add simple CMS and email-to-board features and this will start knocking at the door of the millions of Drupal and Joomla users out there for basic functionalities.
