If your organization is thinking about rolling out Subversion (or if it has recently done so), or if you are a professional trainer, now you don't have to reinvent the wheel when it comes to training users on Subversion. The free, open-source SubTrain course provides a set of PowerPoint slides, plus exercises, "cheat sheets" and more which you are free to reuse and customize. You can also contribute additional materials and or improvements to the existing materials.
We think the open source concept applied to training materials is an exciting new idea and we hope that you will find it beneficial. So hop on over the the Polarion Community and check out SubTrain!
