<p>Sorry, I'm new to SVN and I looked around a little for this. How do you mark a major version in SVN, kind of like set up a restore point. Right now I just setup my server and added all my files- I've been intermittently committing different changes. When I have something in a stable state is there a way to mark this so I can easily revert back to it if necessary?</p>

Sounds like you're looking for tags.
