Before you can start using watches, you need to modify at least two files in the CVSROOT directory of repository.
In the notify file, you need to establish how the notifications will be sent out. Typically, the entry is simply:
ALL mail %s -s "CVS notification"
The change then needs to be committed to the repository.
You also need to modify the users file to include the CVS userid of each user and their corresponding e-mail address:
dyork:dyork@e-smith.com
With a new repository, you may need to create this file. You then need to add and commit the file.
If you are adding the file, you also need to add it to the checkoutlist file in CVSROOT.
