Welcome to the forums Robin.
That's a very good question and you came to just the right place. The Current News Headlines widget on your main screen works with a web standard technology called RSS. Most news websites, blogs, etc use RSS. Just look for one of these icons (

) on the website you want to subscribe to.
To get that RSS feed into your main page paste the RSS link to these forums and we'll add it for you. Simple as that.

Hopefully those are the types of headlines you're interested in. If you need help finding something in particular let me know and I'll be happy to help you out. Then once you've found the links you want, just post them here and I'll get them added.
