Several months ago my friend and colleague Jesper (aka Graffen) got the idea to make a free public SVN hosting service.
I know, I know - several of those exist already, but this is awesome because it's so simplistic, easy to use - and without any rules about having to do OpenSource, etc. bothering you.
You just go to the website, create users and repositories and you are ready to go.
I've already started using it on a lot of my pet projects. It's so much nicer to have even your crazy-idea-personal-projects under source control. And Subversion (SVN) source control have been one of my favorites for a long time.
All you need to be running with SVN and this awesome service is just a SVN client and access.
Great job, Jesper!
