That is indeed a very interesting site, Maggie. Thanks for posting it. For those who may be interested, the 130-page 'Compendium' is available for download as a .pdf file but the link to d/l it is broken. I've advised the webmaster but until they fix it, if anyone wants to d/l it, use this link; http://tinyurl.com/g6y8m It's quite a large file (6.88MB) so will take quite a while if using a dialup modem.
