WLW support is coming in the 3.5 version of the blog which is in the release tracker right now and should be available soon.  Our company, IT Crossing, has also released a product called metaPost which allows you to manage multiple types of DNN content from within Windows Live Writer.  The Community Edition is free and it ships with a blog module provider along with other providers for DNN and third party modules that make it easy to manage a variety of your DotNetNuke content from within Windows Live Writer.  See my signature below for a link to the site where you can find videos that make it easier to get up and running with Windows Live Writer.

I notice that the new blog module failed out of the release tracker on 8/13/08.  Is this getting fixed and put back into release tracker soon?  I really want the WLW function but want to stick with the core modules.  thx in advance
