4.3.5 is primarily bug fixes and yes it is stable (or I have found it to be ;-).
I am not familiar with Moodle, but here is a little info about our LMS:
- It is a DNN Integrated LMS
- 100% SCORM 2004 Compliant
- Fully Integrated Certification System
- Objective Based Learning Object Assignment
- Auto Discovery Services
(take meta data of a user, group, or cert and lists appropriate content sorted by relevance)
- Master Child Portal Content Pushing and Assignments
The list goes on and on. The LMS is flexible enough to be used by medium sized corporations to large enterprise corporations and educational institutes.
Future Add-on will include, Licensing/Certificate Archiving, Integrated Support Desk, Commerce/Sales/Costing (allows you to sell learning tracks, cost training, and invoice clients or pass costs to department budgets), Virtual Classrooms, Surveys, and Project Management (primarily for use in developing curriculum, training tracks, certification tracks, etc).
I hope this gives you some ideas of what it does not and will do in the future.
