Hello all.  I'm doing some work on an existing DNN 4.0.3 production site, and wanted to add the Blog module to a page.  When I looked in the drop down menu for available modules, Blog is not listed, nor is there a folder under DesktopModules for the Blog.  Was the Blog not available in 4.0.3? 

I downloaded the most current PA, Blog_3.02.00_Install.zip, and was going to add it but then stopped because I wanted to check compatibility.  I would like to avoid upgrading this site if possible, but can I add the Blog_3.02.00 module to a 4.0.3 site?  Thank you all for your time.
