The section is not referred to on the current runrev.com site that I can
tell any more, but you can still directly access the old scripting
conferences here: http://support.runrev.com/scriptingconferences/

There is a very useful stack (number 16, Text munging, which includes regex)
by Alex Tweedly. Whatever the RunRev version you have, the regex is still
current, and very helpful to get to grips. Includes a sample email address
extractor, which shows just how to use it.
