School would be an awsome place to start you social network site do it at the end of year 11(UK i am guessing) where everyone is leaving which would cuase all the people to be sad as their are leaving their friends
This is until they find your social networking site where most of the school is on. and volia you have loads of new members
the main thing is to talk to people about it just a couple of months back so people will know about it.
Just my idea
While this does sound like a good place to start, and I don't know how this works outside the US, but there are schools out there who are strict about what kinds of sites you can and can't visit, and more often than not these do include Social Networking sites. So yes, while school would be a good place to start as far as promotion goes, I would take extreme caution as many schools are strict about what sites students can and can't visit.
