I'm a tad confused about what you want to do. You want TWO bloglists, or just MOVE the existing one into the sidebar?

Either are doable. Edit your skin(s) _main.php file. Find the part of the code that does the bloglisting and move/copy it to the part of the file that contains the sidebar content.

We don't use a bloglist, but looking at the Phoenix version of the Custom skin, the bloglist is simply a PHP require statement for the bloglist.php file (also stored in the custom skin folder).

<?php
	// --------------------------- BLOG LIST INCLUDED HERE -----------------------------
	require( dirname(__FILE__).'/_bloglist.php' );
	// ------------------------------- END OF BLOG LIST --------------------------------
?>

Style the bloglist to your liking in the custom CSS file and/or edit bloglist.php to your liking, as well.

Hope this helps.

Cheers,
