Yahoo webmaster tools

Hi guys,

I was just wondering. All search engines webmasters tools are really understandable, but Yahoo is a bit messy to me. Could you please explain when i submit a feed of my website will automatically gets indexed or I need to do something more? I mean that it's been already about 2 months then I have submitted the feed in Yahoo webmasters tools, but still no indexed pages appears when i login to check for them. Thank you.
