exec via PHP?

Plugin works as stated, but I’d like that functionality in the Front End.

Agonistas.com has a page called “Bloggers”, containing PHP code (via Insert PHP Plugin) to display a list of the bloggers and the number of posts for each. Folks can thus read their favorite blogger without having to wade through the entire website (77000+ posts).

Page contains:

[insert_php]
wp_list_authors(‘optioncount=1&orderby=post_count&order=DESC&number=5000′);
[/insert_php]

Clicking on a blogger’s name displays their posts according to the usual WP Setting.

I would like to build a similar page to display commenters’ names and clicking on a name would display the posts being commented.

Is this feasible? Can you give me the PHP script that would do this?

Thanks,

Ray Saunders
