i have used the system for more than 2 years now, as a consultant we are using it to share our expertise and training material in various teams across different countries.The integration with Xerta API means that the modules can be easily integrated into our product line.
The support service from Xpert has been excellent, they are very responsive and always willing to help. I would like to see some new features added for the user experience. We use their service mainly for sharing the content of our experts, but also for publishing training materials.
