I still very new using Subversion.
Is it possible to have a working copy on a network available share (c:\\svn\\projects\\website) that everyone (in this case 3 of use)
I think you're selling your team short. Non-devs can easily learn to use SVN, especially with something like tortoise. If you're gonna go through the trouble of setting up SVN, then just give everyone a separate login and let them work on their own local working copy. Do a quick and dirty CruiseControl automated build to pull from SVN to create the staging site content. It's just a little more work and the result will be so much nicer.
