I also wanted to use the blogging feature of Flock to post to my website that uses Joomla 1.0.13 but unfortunately try as I might I was unable to get it to work.

I was also frustrated by the lack of documentation. From what I understand the extension .zip file comes with 2 files, one of which you have to manually unzip on your server, the other you have to install as a mambot. Unfortunately it didn't say so anywhere I could find.
