WP DISCUZ for subscriber WPForo for others roles
It's possible to install WP Discuz only for subscribers and WPForo for all others roles ?
There is no way to use wpDiscuz subscriptions with wpForo. wpForo has all subscription options. I don't see any reason to use the feature of other plugins. wpForo allows you to subscribe to your topic, to replies of that topic, to a forum, and even it allows following to certain user to get email notification when the user opens a topic or reply.
