Dear Jacob--the simplest way for you to get the info you need is to access the PD list archives...you should have gotten the info how to do this when you joined the list. If you have lost it (it happens! ) just send email to <[log in to unmask]> and ask John Cottingham to give you the "how to"--he posted a new set of instructions within the last week. The materials from past posts are collected there, and you can get them for many subjects, rather than have to ask folks to repost them to you. Neat! Camilla Flintermann,Cg for Peter 78/7 Oxford,OH
