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)
In my experience it will work just fine out of the box. At my company we have had this setup for a number of years and not experienced any problems (outside the obvious ones of having a shared working copy).
You should however look into having separate working copies and a trigger (hook) that updates the shared location on commits if you need a "live" version of the site.
