Reply to Steve,
I just asked what I thought was a very simple question. It was not intended to be the stimulus for vast changes! This newsgroup could do with some moderation. Wandering off the original topic is normal, not just common!
The the interesting threads are the OT ones. Particularly the OT regarding the subject line but still in CS.
This comes from the point that if some thing was on topic and interesting, I would have already looked into it. So the interesting things I don't know about are general OT.
