Stephanie Helsein one of the most active Koinup member has been so kind to post a slideshow tutorial to help some students to join Koinup. I asked her to post the "how to guide" on the Koinup blog, because I thought that some readers could find it very useful. If you have some doubts on how to upload contents, add tags, join groups, etc on Koinup, then this guide it's a must read. The tutorial is specific to join a group created by Stephanie, but it does help to get familiar with all the Koinup tools and features.
If you're more advanced you can drive some inspiration to use the Koinup storyboard tool
