I'm fairly new to DreamHost so I'm not quite sure how to go about doing this... I want to add additional users who can only access certain folders. More than one person works on my website and I understand how to add new users, but how do I restrict their access to a particular directory? For instance, I want to restrict "bob" to his folder "bobsplace" which will appear as the sub-domain bobsplace.mydomain.com. How exactly would I manage this?
