Are there any good LMS sites like this on suitecrm/sugarcrm?

SuiteCRM is a CRM system. It is not a Content Management System like Wordpress/Joomla. Nor a framework like CI/Laravell/Yii.
We can deploy new modules within it and can extend its functionality via relationships and fields. But there is no LMS like you want.
