Electronic mail is the single most important tool for collaborative work.
The following mail facilities can help this process. It is possible to send any file type to another user using Eudora.

They receive a copy of the document that they can then edit, and send straight back to you. See the Attaching Documents section of the Electronic Mail workshop.
