I've been hacking on our template a little and came across the wp_list_authors link which is exactly what I've been looking for.
I've added the following fragment to sidebar.php
<?php wp_list_authors('show_fullname=1&optioncount=1&feed=rss'); ?>
and it seems to work perfectly for all but one author (me!) where the link only points to the first article I wrote, and not the other 12. Anyone any ideas on whats causing this?
I did have the 'admin' account configured with the full name of 'Stephen Mulcahy' in the past - could this be causing this problem here?
