Seems like there is a lot of functionality but rather complicated. Adding extensions and having to add editors to edit. It seems that Joomla is for folks who have done a lot of web page stuff before. I am sure all the different options will make every Joomla site different rather than how (many, but not all) Wordpress sites look similar. 

The filters look interesting. That can have great uses for libraries. So I am about an hour into it and want to follow along, but I have yet to get an email for me to login. Sounds fairly easy but time consuming. Great for customization. Found the email filled under junk mail.
