Sitecore solution


I have a Sitecore solution and would like to integrate Telligent community. As shown here we can use the free version and it is free until you would require additional applications such as forums, QA, or ideation. My question is when I installed the application I see an expiration date on the licensing page. Does that mean it is free for only for a certain amount of time as well? Or can we continue to use the product after the expiration has passed?

Thanks and Regards,
