This weekend a new version of joomla! turned up in portage. 

Although this was a first for me and I have made some customizations, it turned out to be a fairly simple task to upgrade from version 1.5.1 to 1.5.3.  I made some notes and wrote a shell script to make this task easier next time.

It's beginning to look like porting groja.com from PHP Nuke to joomla! would be a very good idea....
