the folks who were being sarky about 'guest' posters have obviously not been made into guests, unbeknown to themselves, due to their cookie (?) doing something (whatever?) as has occasionally happened to me and others I know- - - !!!!
Sometimes guests assume they are normal posters under their own name / pseudonym -- - and only discover they are gueats by accident.
Also - if someone is new to the site then perhaps they don't realise they ought to register, just wish to ask a simple Q of regulars. Perhaps we should be gentle with them, not sarky - - - --
