Hi Walter,

Indeed you are correct I should be using a VCS but I really just gave up
with it, I was using Git + github to push externally but its such a
administrative headache when you have lots of web servers. Has anyone got or
seen a good guide on using a local Git repo in this way as I would be
interested in going down this route if I could make it simple and easy. I
agree with HA-NFS it also looks to be more complicated than it should really
be.
