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.
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.
