What I'm looking to do is to create a library of template options that all contain the same dummy content but have different designs. It seems to me that it would be by far the most efficient way to do this to start with a single master site and to switch themes, creating a new blog template for each theme. The problem I'm running into is that when I try and do this the new blog template I create overwrites the first one, even though I give it a different name and description. Am I doing something wrong? What would be the most efficient way to go about this?
