 This is a WordPress plugin (WordPress › Blog Tool and Weblog Platform).
~Changelog:
0.5.1 (Jan-12-2006)
Bug fix to get_author_profile() for author query call.
0.5 (Jan-08-2006)
WordPress 2.0 fixes. Added three new variables:
 $author_jabber (author_profile('jabber'))
 $author_nicename (author_profile('nicename'))
 $author_displayname (author_profile('displayname'))
$author_displayname is the name format users select under "How
to display name" on the Users control panel.
0.4 (Jul-11-2005)
Added 'display' parameter to author_profile(). If set to FALSE,
will only return the value, and not display it.
0.3 (Jul-09-2005)
Code changes for WordPress 1.5. If used without specifying user
ID in "author.php" template, will profile the 'current' author.
0.2 (Dec-13-2004)
Added two new variables from outside WordPress' user profile set
(but still considered part of it):
 * $author_posts (number of posts for author)
 * $author_posts_link (link to all author's posts)
There's also a new function: author_profile(). This merely echos
the values of the variables--for anyone who prefers doing things
the WordPress way.
