Otto42: jzahlaway: I told him exactly how to do it above:
It's very easy, really.
I will admit that I may have far less knowledge than everyone else who reads these boards (though, the multiple, similar, unresolved threads on this topic that I've found would suggest otherwise), so forgive me for feeling that posting nothing more than "wp_list_bookmarks('show_description=1');" doesn't explain "exactly" how to do it. I figured it out on my own, and if I were asked "exactly" how I did it, I'd describe it like this:
1.) Go into wp-content/themes/[theme you're using]/ and open the sidebar.php file.
2.) Find the line "<?php get_links_list(); ?>" if you are using a pre-WordPress 2.1.x "sidebar.php" file, or find the line "<?php wp_list_bookmarks(); ?>" if you are using a 2.1.x version of the "sidebar.php" file.
3.) Replace the respective line described in step #2 with "wp_list_bookmarks('show_description=1')"
