[Skunkworks] Joomla Help

Ji all, Got a question to the joomla experts out there. Is there a way of having multiple sites running on the same joomla installation? Or even let say there is a joomla installation on the root with the other running as a sub directory but one instance.. -- Regards Jude Mwenda "Was ist mein Leben, wenn ich nicht mehr nützlich für andere."
