Not every organization can afford a full-blown LMS (Learning Management System). Sometimes, that's not even what you're looking for. If you have been wanting an online environment to bring together a group to study where you can have discussions, online chat, share files and collaborate, check out the social learning tool ThinkBinder.com. Super simple to setup and super easy to use.
You'll notice it is designed for study groups of students working on a problem or collaborating in a class. I can see it being used in training in much the same way. For an excellent video demo, check out this.
A year ago, Echo360 purchased ThinkBinder, but I haven't noticed much change in it. Echo360 is a neat lecture capture program, so it makes sense to bring these two companies together.
