Subscribe button & share buttons (social media)

Hi Ben. I can not find information anywhere on how to set up a “subscribe via email” button and link. The information on the WP forums is not very good and a lot users report failure.

Also, I would like to have “share” buttons for various social media under each post. For example, I would like people to share my story on THEIR Facebook page by clicking on a FB icon.

Can you please tell me how to set these two things up? Much appreciated!

P.S. I’m excited to try out the new CSS collection. Just need to get thees two basic things up first and then launch!
