Share Web 2.0

We have a Yahoo Group and a WordPress Blog. There is a feed from the blog and we are pushing postings from the blog to Twitter. But I’d love to be able to push our blog postings to the Yahoo group so I don’t have to duplicate efforts. Also would like to send the info to our mySpace page….anyone know how to do this?

On the facebook home page, there is a link to a page that shows all the groups joined recently by your friends. How do you stop the groups you join from appearing on it?

I occasionally need to forward e-mails that contain links to web pages to a yahoo groups e-mail. However, when the e-mail goes out all links and images get deleted by yahoo. Help!
