>Thanks, I appreciate your patience. The fully qualified name "Frequently Asked Questions" must have eluded me. One further question though, when I did previously click on the "book" icon, I did a search on "Registering", another one on "Registering/unregistering" but did not get the FAQ which is clearly in the system. I must not understand the search syntax -- I know it rejects quotation marks, I know that it doesn't like the + and - like some other engines use, but not finding the keyword "Registering" when it is in the title seems constrained to me. Thanks again, I did find the FAQ that I was seeking.

Robin, search with 'register' and you'll find the item you want and several other interesting snippets.
