I'm trying to get on the mailing list... Am I doing the right thing to get added?By sending the above email? No. Instead, you want to go to http://www.debian.org/MailingLists/subscribe and select the "debian-user" list and then scroll to the bottom and enter your email.caf
You'll then get an email, to which you must reply (from the same email address). Then you'll get a confirmation saying you're subscribed.
