Kim's Very Long and Boring Email Text File about File Versioning and Servers.

Hello all.

This is A Very Long and Boring Email Text File about File Versioning and Servers.

Please feel free to point and laugh, but this is all stuff that I've learnt the hard way, and that we should start to do as we get bigger. It doesn't take long for all this to become a habit; something you don't even think about doing. When it's working properly, it offloads a load of organisational stuff from your brain, too - which is nice, and what computers should help you do.
