I've setup a page containing information relating to the NNTP Posting Plugin for NewsGator. This page will give you more detailed information, a change log, and other stuff (not yet defined). By using this page you can keep up-to-date on the NNTP Plugin.
As a side note, version 0.5 seems to be the tip of the iceburg for this plugin, so after a few weeks it may be moved into 1.0 status. I've also setup a new forum where we can discuss the plugin, get support, and ask for enhancements. Hopefully all this will lead to a community driven plugin.
