Now I'm evaluating http://www.assembla.com and so far import is working. It's a different approach because you need to sign up for a developer acount and then you can sign in into projects, become members. So in order to give rights to another user these have to register with assembla.
Don't forget that you can find a lot of information on svn in the following free ebook: http://svnbook.red-bean.com/
I'm now getting into assembla and it is all for free and very usefull so far!
