You can delete the original text by selecting that item from the menu, or you can manually copy and paste a message.
In the context of a listserv discussion, for example, it's considered a basic courtesy to edit out the irrelevant portions of an email to which you are responding. This courtesy is impossible on the BB. Some lists actually forbid top-posting, which the BB effectively forces upon the user. And if I manually copy and paste, I must also manually add the '>', which is the sort of thing computers are really much better at.
I've never seen any other mail client, anywhere, with this weird limitation.
LogicMail, which is still in development, does it right. Perhaps some other aftermarket email software will also handle this.
