And FWIW, yesterday a woman associated with publishing shared with me that the laws regarding the use of material from Internet discussion forums such as this one are very murky..it's too new a phenomenon. However, she recommended that when quoting something off of the Internet the Citations/References should be presented as follows:
Author's name [or author unknown in the case of Guests; probably with the full Guest name if he or she adds a name to 'Guest']; date [day month year] that the quote is retrived; title/subject; retrived at [add URL]
