MetaWeblog API: project started in SVN
A little while back I started an Umbraco MetaWeblog API implementation. I know a couple of other Umbraco developers were interested in this functionality so I have put it in SVN with the other Umbraco extensions.
As I am really busy at the moment it is unlikely I will be able to do anything with this for a while. If you want to contribute to finishing it off, drop me a mail and I can run you though how to get it up and running.
