How to get licence for community edition
A license can be purchased by contacting Sales: https://www.telligent.com/about/contact/ . The free edition must be upgraded to the latest version to maintain its license.
To upgrade the free version, you must request the free version again and run the upgrade per the instructions. Click the "Get the Free Edition" button on the homepage of this site.
I should be clear that I am trying to read the documentation https://community.telligent.com/community/10/w/user-documentation/62009/how-do-i-upgrade-telligent-community which has me confused about how to contact support to get the installation package.
