New to WordPress plugin development of any kind. Let's just get that out of the way.
I'm trying to find or modify a plugin that would allow users to sign up for "alerts" when a new post is published. They could sign up for email OR SMS (via SMTP) notifications, OR BOTH.
Something maybe like the alert enrollment on this site: http://www.ridepatco.org/schedules/enotification.asp
Any thoughts? Or is the not possible with Wordpress?
Thanks in advance!
