Hi Ken,

joomla http://www.joomla.org/ is the winner of 2006 Open Source CMS 
Award. There are plenty of plug-ins and extensions (even if some are 
payware) but if you need SSL support, you must wait for version 1.5 (in 
Beta now). It misses also some performance-specific features, like 
"database replication" and "load balancing".

Drupal is the second, and Plone the third.

Look at http://www.cmsmatrix.org/matrix/cms-matrix and compare Joomla, 
Drupal, Plone, Midgard CMS, My Source Matrix, Saurus CMS Free,  
worksystem, etc. ect.

Ciao,

                Enrico
