Along with the regular version of CourseForum, we are also pleased to offer a free version!
We realize that not everyone needs all the advanced features found in the full version of CourseForum. We're offering the free version to provide opportunities for more people to use CourseForum, even if they're not able to purchase it. Obviously, we hope some people will choose to upgrade to the full version later, but if not, that's just fine with us too.
The product details page describes the features that are not available in the free version.
The free version supports all the features you'll need for effective collaboration and content creation in your courses. There are no time limits, limits on amount of content you can create, etc. Its perfectly reasonable to use the free version for real, extended use in your courses.
Just download the software as usual. If you don't provide a license key, you'll be running the free version - simple as that!
If you decide to upgrade to the full version, you can enter the license key in the same software you're already running. Or, try out the full version by requesting a free, time-limited demo license.
