Subscriptions to GPL-licensed software (such as JCal Pro®, sh404SEF® and Advanced Search) provide access to the extension documentation and a download service. No warranty, guarantee or support is included as described in the terms for each extension. If your subscription is expired, you will need another to download products updates.
This commercial GPL business model causes confusion for some users who are accustomed to commercial proprietary business models wherein support and service are included. However, the extremely low prices of our subscriptions reflect the lack of these services common for commercial proprietary applications.
