I would like to get the e-mail address where to post a recruiting
advertisement for about the top 10 Swedish business universities
(Stockholm, Lund, Uppsala...)

So our purpose is to recruit students from these universities: if you
find addresses where I can post the advertisement directly without
e-mailing it somewhere, then this is also ok.  Similarily: if you find
one address where I could contact all those universities in Sweden,
then I would be even more happy. (in Finland there is one: (
http://www.aarresaari.net/english/index.htm ) => so if you would find
similar service in Sweden, then I would not need anything else)
