most email applications show the email message that is about to be sent, including those that are forwarded, you just simply delete the section of text that shows who sent it to you etc
I receive an e-mail showing everyone to whom it has been sent. I want to remove these names before forwarding. I am using AOL to send e-mails. Hope this is enough information.
When you click on forward and put in who to you are then able to highlight old names and addresses and hit delete if you have any problem, delete a few at a time works for me and all my friends.
