Rapidweaver 5 form multiple emails

Hi yes I still use rapidwever 5 ( for several reasons one being the publishing is more reliable tahn rw7 's which I cant seem to getto work) . The present problem however is simple . I want to know the syntax I should use when sending the in built rw5 form to multiple e-mails . I have tried several guesses (, : ; etc.) but none have worked . Does any ones memory strech back that far to let me know )
