I'm now using SVN on TAPoR for the AdaptiveDB codebase, and because it took me quite a while to figure out how to get it working properly, I'm going to document it. Commands are issued over https like this:

mholmes@spudbuntu:~/WorkData/adaptivedb/site_dev$ svn co https://revision.tapor.uvic.ca/svn/adaptivedb/trunk trunk

To use a new repository, do a checkout first, then start using svn mkdir etc. to set up the repo structure. If you're on Ubuntu, beware of this bug, which is supposed to be fixed, but which still blocked me from getting access for a while. The solution is to delete rm ~/.gnome2/keyrings/login.keyring (or whichever keyring SVN is trying to use, and failing -- sometimes default.keyring).
