MQ - when faced with a problem (the minimum letter search is, I believe, 4 except for a few selected '3s') it requires a little lateral thinking to solve the problem.
'Vspeeds' gave me 2 pages going back to Nov 2000
'Decision Speeds' 5 pages back to 2002 - not all relevant
JT's excellent 'Sticky' at the top of 'Tech' has quite a few links
Whilst on the 'search' topic, please NB it will produce a maximum of 500 finds (at the moment) so sometimes you need to put a little work into the search phrase.
