How do we use categories. I have several created in Joomla but the never show as options in Easy Discuss. How can we create them for easy discuss/ Can they b created in new posts and then selected to allow viewing a single caegory?
Do you mean you noticed that the system auto-create discussion post if the user creates a new Joomla article on the site?
If yes, you can decide what Joomla category article post will be fetched into the Easydiscuss component from this plugin "Content - EasyDiscuss".
