Just what I was looking for: a plugin that let me reuse the joomla installation to set up 2 sites with similar/shared content.
Easy to use!a, maybe the allow_call_time_pass_reference set to On restriction can cause problems with some not owned servers ( not may case for now :)
Just had some problems to set as start point an Blog Category menu, don't know why. The rest works very well.

Definitely I would recommend it. At first I thought as Flutje there was a problem with the closing of the menu when mouseout, but as I added more submenues I realized a submenu is closed only when another one is opened, and this is a friendly feature for the end user. Maybe would be nice to add the option to close always the submenu on mouseout. It's a pity this extension is not being maintained anymore. Let's see if someone else takes the torch :). Good job!
