Glad I found this thread.
I've been looking at Joomla, JMS Multi Site, or rolling my own site with php and maybe codeigniter but maybe someone can point me in the right direction.
I'm wanting, for example, to set up a portal for my county.
First, each town in the county would have their own section where the "town manager" can write articles and post events to the city event calender, etc. These would also contain some static pages "Town History" etc.
Second, the home page would pull and display the most recent articles and events from all town sections.
Last, of course, visitors could use the menu to switch between towns
