I'm planning on creating a new site that sells online courses. I want some articles to be publicly available BUT I also want to restrict access for certain articles to paid customers only. Each article will have a public teaser - but I want only paid members to see the full article. Whats the best CMS system for this? I am seriosuly looking at joomla - but should I be looking at something else?
It's possible in Drupal to make the teaser as public access and full article only for members/paid customers. There some methods to do that : with some modules or with short php code.
Same with DLE CMS. It's more a visitors groups permissions thing, in basic approach it can be made in some minutes/within an hour. As for video information for courses, you can host even 1080p.
