ASP.NET Elephant - ASP.NET Tips, Tricks, Tales and Trails

This is my first post on ASP.NET Elephant - ASP.NET Tips, Tricks, Tales and Trails. So Why the Elephant? Well I don't have a memory like an elephant and have long realised that I need one - so welcome to my ASP.NET 'social memory'. Every now and then I'll be posting ASP.NET tips and tricks, developer tales, and resource trails.
