I’d like to introduce SO: as a prefix of email messages to signify that there is no body text. The “SO:” stands for “subject only” (there is no body message).

I like it because it mimics the RE: and FWD: prefixes that email clients already use. In fact, if you hit send on a message with no body text, the email client could insert “SO:” in front of the subject you wrote.

This has all the benefits of EOM, and I like it better, but since EOM hasn’t really caught on, is it too much of a battle to get SO: adopted? Should I just give in and use EOM? Is it worth explaining either of them, or should I just continue to have both a subject and body text on every email?
