Hi Dave. I'm from the same era (also starting senior school in the year of the drought), though I wasn't in Amersham then. However, I too have been in IT for nearly 20 years, though not as an uber techie (I translate the techie stuff to real language that (hopefully) users can understand).
I left Challoners in 1994 but was born in the year of the drought... So has there been a thread on who works in IT then? A lot of forum members sound like they do - I certainly do - in fact if any .NET developers fancy a permanent role I'm currently interviewing for 2 developers to join a Microsoft Gold Partner in Chalfont St Peter. I hadn't thought to ask on here before, but you never know who's reading... I have a job spec I can send to anyone who might be interested - feel free to contact me for more details.
