'More than happy to give an example, how do I attach a file to this thread ?' - simple, request those interested in receiving a copy, to send you a 'Private Message' containing a valid e-Mail address.
When you create an e-Mail message, place all those who respond in the 'Bcc:' field [not the 'To:' field, not the 'Cc:' field] (each e-Mail address separated by a comma and space). In the 'To:' field enter something like 'rtf@mailinator.com'. Naturally, attach the '.rtf' file(s), in question, to the e-Mail message.
Finally, do not distribute or send any future e-Mail's, to the e-Mail addresses supplied. If you have a problem or problems - post them, as you have 'How do I open MS created RTF files ?', on the 'MacOSX.com' web site (and / or equivalent web sites).
