look at email subscribe / newsletter plugins.

thanks for your quick response.
No, I do not mean a newsletter subscription. I have one on our other site, that news letter gets sent to the people registered to get the newsletter.

What I want is simply allowing people to register, and when there is a new post published an (automatic perhaps) email gets sent to the people who have registered saying that there is a new post. The post itself does not get sent out to subscribers. People have to come to the site to read it.

I hope that this is a bit clearer.

Co.

Ps, thanks, moderator, for transferring it to the correct forum ??
