Adding Facebook Plugin to front

On facebook I can generate code for a "like" button to add to the front of my website.

How could I add the code below to index.php?

<iframe
src="http://www.facebook.com/plugins/like.php?href=http%3A%2F%2Fwww.facebook.com%2F%23%21%2Fpage
s%2FTaboo-Exchange%2F119140481434304%3Fref%3Dsgm&amp;layout=standard&amp;show_faces=false&amp;wi
dth=450&amp;action=like&amp;f alt=verdana&amp;colorscheme=dark&amp;height=35" scrolling="no"
frameborder="0" style="border:none; overflow:hidden; width:450px; height:35px;"
allowTransparency="true"></iframe>

I tried adding it all the way at the end and it wouldn't work. It would just load a blank white page.

Also, how can I change the font color in the orca forum?

Just create a HTML block in the admin panel and paste that code inside the block, did you tried that?
