Announce List

I’m trying to set up an announce list on my site. I changed all the forms in the fields that I was supposed to, and I left the values for the pages blank. (SubscribedURL, etc) However, when I try to sign up for the list I get:

Attention Webmaster! Form Misconfiguration

Your list “” at domain “” is invalid!
(The list address is invalid: alias is blank).

I have the name of the list filled in on the “FromEmailAddress” field and the domain name filled in on the next like like it instructed. Am I doing something horribly wrong here?

Ah, nevermind. Figured it out myself.
