Well, you could actually forward it to yourself and then forward it to whichever staff person you want and if they inadvertently lose it then you will still have your unedited note in your messages under deleted files. Or when you forward it to your editor just don't delete it in your mailbox. Once you close out of AC your deleted messages are not retrievable.
Personally, I don't want just anybody in my office to be able to access a note that I'm working on. Others in the office are able to access the chart and work in the same chart, they just can't access your unsigned note unless you send it to them. Signing it makes it a permanent record....no way to change it. Part of the certified emr thing.
