How do I delete all the addresses from incoming E-Mails be for sending it on to some one else?

Sure you can do that.

You have to click on forward first----then highlight those previous addresses and press the delete key on your KEYBOARD, and--zap--they're gone. Then send it as usual. The outgoing mail reflects the changes.

With Yahoo-----sometimes---if, at first, you see nothing in the forward window--you have to click the down arrow next to the forward tab and choose "as inline text". That put everything into that window, and at your disposal for editing as you wish.

If you are going to forward something you recieved by email, you really cant delete all the previous addresses, the only way I can think of to send on to someone would be if you got info on where the info is so you can just email someone else with an attachment, therfore your email would be the only one with the subject-- am I confusing you?
