If you need the ability to import from another module that is not supported then please open a support ticket at http://www.mandeeps.com/support.aspx and we'll happily accomodate your request. 

INSTRUCTIONS:

Download the Live Blog Import.zip and extract/unzip the Mandeeps.DNN.Modules.LiveBlogImport.dll to your DNN Installation's /bin directory. 

Login as Superuser/Host and navigate to a page that has Live Blog module instance.
Navigate to Manage Blog > Settings > Import and follow the prompts. If you need assistance, please open a support ticket.

Note: You can safely delete the Mandeeps.DNN.Modules.LiveBlogImport.dll from /bin directory after importing your content. This reduces the memory footprint of the site and increases performance.
