Clicking the link in the e-mail that was sent to you is what confirms your subscription, then automatically redirects you to the D-14 enduro web site. This double opt-in method helps prevent malicious use of the mailing service and propagation of spam.
After confirming via the link, you should get a follow-up e-mail stating that you have been successfully added to the mailing list.
I used the existing D-14 distribution list (about 150 names) I got from TDunn and BV to do a mass send-out for the initial opt-in campaign. I didn't have everyone's e-mail (like BBarel's). For those folks, they can sign-up manually with the link provided in post #1 of this thread.
The D-14 enduro web site is in the process of getting moved to a new hosting provider. Soon after that's done, the mailing list subscribe / unsubscribe box will be available directly from the home page.
Make sense?
