What disappointed you at the end? We need developers such as yourself to present what you are doing & learning. Sort of like the video done to demonstrate your LED appliance. We are also learning how to 'meet' as we go along.

The disappointing thing for me was that it turned out to be a Microsoft tools / .NET forum, and not a general developers forum, as I'd understood it to be. I learnt, too late, that it was actually an expanded AfricaDotNet meeting. The speakers, so-called Microsoft MVPs :), were patronising, and in my opinion, very ignorant.
Let me just say that I won't be wasting my time in future!
