The core of Invision Community contains the central functionality that powers the product and is therefore required to use the other apps. It provides functionality like member management (registration, profiles etc.), themes, languages, search and much more.
Our self-hosted licenses renew on a 6 month basis, and provide ongoing access to support, software and services. If you do not renew by your expiration date, your software will continue to function. However, support, software downloads and additional services will be unavailable until you renew.
