Hi,
what enables widget on sidebar/footer is this piece of code:
<?php if ( !function_exists('dynamic_sidebar')
|| !dynamic_sidebar() ) : ?>
It probably means little though, so you might want to learn the whole thing up at Automattic.
Hope this helps.
Hmmm … alot of interst on this topic. Okay, I’ll bite, here’s an article on the topic you may find useful entitled Add Widget-ready Sidebars to WordPress Footers.
And another article about the same entitled “Howto: A Widget Ready Footer.”
I didn’t write them, but I sure am going to use them!
