For LoudBlog users
PodHawk was developed from the LoudBlog podcasting programme, by Gerrit van Aachen and Sebastian Stein (many thanks, guys, you did a wonderful job!) Several of PodHawk's built-in themes match LoudBlog templates, so you will probably be able to convert to PodHawk while preserving the 'look' of your site.
The PodHawk download package contains a text file "howtoupdate.txt". This explains how to upgrade either from an earlier PodHawk version or from LoudBlog 0.8. (If you have an earlier LoudBlog version, you need to upgrade to LoudBlog 0.8 first.)
