Thanks for posting this stuff. Very interesting indeed, especially the Chinese factor. The PC vs Mac thing is a bit like the Canon vs Nikon thing!
Just on a vaguely related matter ... our club is looking to conduct more of its activities via an interface like yours, and is looking at on-line mechanisms. This is Joomla isn't it? How much knowledge does one have to have to set up a photo club using this software - is it purely a programmer's realm or could any reasonably computer aware person have a decent crack at it? (without meaning to suggest that this site was easy). We need to bring our club further into the 21st century.
