Yesterday, in preparation for a workshop I'm running this week I created a new set of slides demonstrating the basics of creating a blog on Posterous. As I mentioned last month, this semester I am using Posterous to have my students contribute to a group blog in which they summarize what they learned each week.
If you're introducing other educators to Posterous, please feel free to use these slides. All I ask for is attribution. These slides have been added to my page about creating blogs and websites.
