I have done some searching through the forums but as when I first came across SilverStripe many months ago and couldn't find the answer then (and stopped using SilverStripe), I still can't find a definitive response showing how SilverStripe would manage multiple separate websites.

Can anyone provide a straightforward description on how (or even whether) a single installation of Silverstripe can manage my (very small) companies website, and that of a couple of friends (very small) businesses ? Does/can SilverStripe maintain separate 'profiles' that would allow this and switch between them easily ?

I'm not a web developer at all but am keen to consider using SilverStripe for maintaining my website & a couple of others, without needing "separate virtual environments" as I keep reading as a possible solution. I don't relish the thought of having to install SilverStripe as many times as the number of websites I'd like to look after.

Thanks in advance.
