I'm not sure that's correct.
I just created a new subdomain: svn.quarter-flash.com
I then created a new project "tutorials". Logging in I can see, in my home directory, a directory named svn and it has the information about the tutorials project in it. I can also see the website that appears to be empty.
In my browser I can navigate to http://svn.quarter-flash.com/tutorials and I can see the project name (with no contents, of course.)
In MonoDevelop, when I try to publish the project I get the following message:
MKCOL of '/tutorials/!svn/wrk/00471e30-dccf-4d24-96a7-9c9f63e1644c/GTKGladeTutorial': 405 Method Not Allowed (http://svn.quarter-flash.com)
Now, this was all set up with the tools in the panel, nothing at all done manually.
