Nick, see that wall next to you, it's more likely to listen and respond than the person behind the changes ;)

IMO it's just pure laziness that things aren't tested on a development install of the site. The vB license allows three installs. One public/active install, one password protected install on an active webserver for testing purposes, and a local install aka on your own computer for easier development/testing.

There are plenty other CNC sites, it's just this is the most popular within the UK.
