Used my home address so that work wouldn't see it. And since I'm not at home, I haven't read the response e-mail, so there may be technical details that I am so far unaware of. Nonetheless, the page says basically, "Send mail to this address to have it propagated. Enter your address (ostensibly to be added to the distribution list) and a password." It doesn't say whe that password will be needed. And since I don't have any e-mail to send to the list (nor do I wish to spam it with a "testing" message), I don't see from that page where a password is needed.
Just curious, that's all.
