Trying to get rss feed to work

[plugy]

Im looking at the rss feed modules in the prestashop 1.5 but what are they?

I subscribe to a drop ship site who has given me a link for new products and another for product catagorys.

As i understand do i install the module and click configure and install the link i have (have done that but get error invalid code) and it displays a box with scrolling products from this site on mine.

Any help i am a "complete dummy noobei".

Also is there a module that when i install a product in my back office it auotmaticaly updates and goes out to my face book like subscribers any help please.
