Actually I've been here many times before August 1998; just haven't got round to saying so here.
At the moment, I'm mostly interested in systems reengineering patterns -- why not visit
www.dcs.ed.ac.uk 
and see?
If you are interested by Reengineering Patterns take a look at
www.iam.unibe.ch and do not hesitate to give us feedback.
