Anyone have experience using Discourse on a Drupal site?
Drupal and Discourse are separate applications, so your question doesn’t quite make sense. You’ll probably want drupal and Discourse on separate servers (it’s much easier than running them on the same server).
But trying not to be pedantic, I’m about to start a drupal integration that has Discourse authenticate against drupal. You might also have drupal use Discourse for comments.
How do you want Discourse and drupal that work together?
