If you do not understand some of the abbreviations or terms used, the Google is your friend. You can also do a search of the forum for any of the many similar cases to yours.
I'd been thinking that a "sticky" here with a glossary/list of abbreviations might be useful.
People like you and the other experts here already go above and beyond with the giving of time, so I'm not asking any of you to do it.
I'd be happy to go off and do the Googling (or "Binging") and put together a document, format it, spell-check it etc, if someone could give me a list of abbreviations to work on.
When done it would need one of the mavens to spend 5-10 minutes checking it to make sure I'd not put rubbish in.
