Listing Authors w/ links to their url

I’m completely green when it comes to writing php code. I was lookin at the codex list_authors tag, and I need help.

On my sidebar, I have the authors of the site listed. Their names are links to all the posts they’ve made on the site.

I would like to make their full names be links to their url, from their profile, as well as display the number of posts they’ve made ex: (24).

here is the tag of code I’m currently using.

<?php list_authors(TRUE, TRUE, TRUE); ?>

Any help would be much appreciated.
