Where can I get the code to pull my Facebook & Twitter feeds into my site?

For Facebook, go to http://developers.facebook.com/docs/reference/plugins/like-box/ and review the instructions in the screenshot below to generate the code.

Twitter is a bit easier.  To generate a code, click this link: http://twitter.com/about/resources/widgets and select “My Website."

Then, simply enter your username, and customize the look & feel of the widget.  When your done, click 'Finish & Get Code.' 

After generating the code, it is recommended to save to code in a Notepad file in case you need to edit the block. 

When you have the code to enter into your site, go to Site Building > Blocks > Add. Then, follow the instructions for embedding code.  When you're finished saving, simply take your block out of the 'Disabled' section, and add it to the block region of your choice.
