WordPress MU

Here's the older version:

http://codex.wordpress.org/WPMU_List_New_Blogs_Widget

I'm nowhere near smart enough to update it for 1.5.1 - I can see some of the differences in how the widgets are handled, but I'd rather not break my install by experimenting.

Let me save you the effort of clicking the link...
Again, need help bringing the code below "up to speed" for 1.5.1 - thanks in advance.

<?php
 function widget_list_newest_blogs($args) {
        extract($args);

        if(function_exists(fimii_wpmu_newest_blogs)) {
                 echo $before_widget;

                 echo $before_title . 'Recently Created Blogs' . $after_title;
                        echo "
<ul>\n";
                        fimii_wpmu_newest_blogs(5);
                        echo "</ul>
\n";
                 echo $after_widget;
        } else {
                echo "Error - function list_all_wpmu_blogs not found";
        }
 }
 register_sidebar_widget('List Newest Blogs', 'widget_list_newest_blogs');
 ?>
