We have been using Trainer Central for two years now. We have built an academy with numerous courses and a couple of hundred students. I decided to simply share my thoughts on what is missing in this service, perhaps you will find it interesting.
- Evergreen webinars(!)
- Affiliate program(!)
- A full-fledged website with settings for full SEO indexing
- Blog
- A/B testing of landing pages for webinars and courses.
- Countdown timer
At least.
I know that some of this list can be done using third-party services, but it is not seamless, expensive, and some functionality is not available at all.
