With Joomla when people can't work out the section's and categories components etc withinn 10 minutes they seem to lose the enthusiasm

Joomla can have a steep learning curve, but once you know what your at, the possibilities are endless, User styles,. different parameters, page layouts, Good clean coded websites and end less components, modules and plug-in’s.
Extendibility was is a major design of Joomla! 1.5. By no means it is needed to do a core hack when you want to add functionality. The framework holds a very powerful mechanism for the extendibility; a new event-driven plug-in framework.


And in 1.5, a designer can change every little bit of html the system generates; the standard output however is still the same as in 1.0 to retain backwards compatibility with 1.0 site templates. This allows the creation of accessible, standard compliant, table less, whatever-the-designer-thinks-is-important, websites.

I've looked at most CMS systems but once you go Joomla you won't go back as the site can be as simple or complicated as you want.
