Hi there, first of all sorry for my bad english, i will try to explain myself the best i can.
I saw in a website a feature where a user subscribes to a sms service, once subscribed, everytime the webmaster add a new post to the specific category the user receive a sms notification in his phone, the sistem uses the google calendar, its possible to have some kind of plugin to wordpress that allow me to do that? as far as i know google have an api to do that and its free.
by the way this is the site: http://www.wareztuga.tv/serie.php?s=Smash&ep=On_Broadway
look under “Episódio 1 – On Broadway” the phone icon.
