It's too easy to make a mistake and delete the header, or create a problem that isn't easily fixed without calling on the help of an overworked listserv manager.<< Is there anything intrinsically dangerous about it? I keep two copies of the header on my disk. One has errors-to me the other has errors to my co-owner. Otherwise they are identical. When we switch of I change the name of the file and send it to the listserver using the CMS command "sendfile". If this can potentially mess up the list I'd like to know about it. (I like not to get bounced error messaages when I am out of town. A few bounced digests can overwhelm my disk, even if my co-owner is quick to take care of them) I'm curious as to what people think.
