On Saturday I did a podcast with phpBB Weekly.  Check out the recording here.  Host Douglas Bell summarizes this episode with "We discuss how a system like Assembla can be useful to MOD authors, or for anyone trying to manage a project with numerous users..."

On Thursday I'll talk with Bob Bloom on the "Joomla eCommerce" show at blogtalkradio.  Bob wants to talk about "the important of source code repositories, and agile development tools..."  Joomla and the other PHP portals like Drupal and Wordpress are an interesting case, because it is not easy to build staging and production configurations from a repository.

UPDATE:  The Joomla podcast is posted here.
