1. Their email will be visible as it flows over the Internet. An encrypted
connection protects this.
2. Their reusable password will be visable over the Internet unless you use
APOP authentication (not bulletproof, but better than a reusable password).
3. They must be educated against using the usual PC email stations at
conferences. These are wonderful places to find all sorts of email left
behind by people who both sent and received email using them.
