Using the GData C# Library, the utility will walk backward in time, from your latest post to your last, saving each post to a local Atom/XML file.
v22.214.171.124 Beta Release (4/2/2008 6:00AM PDT)
This is a minor, just one, bug fix release
Updated to fix a bug where if a previously backed up post did not have a title node, then it couldn't be restored (it would error on the attempt).
Now you should be able to restore them with no problems (but of course with no title either)
