It’s working now with this code:

function get_ID() {
	global $wp_query;
	$thePostID = $wp_query->post->ID;
	return $thePostID;
}

and

<?php bloginfo('url'); ?>/wp-admin/page.php?action=edit&post=<?php echo get_ID(); ?> as link.

EDIT:
These forum can’t display my last solution (the manual one). Here again:

<a href="<?php bloginfo('url'); ?>/wp-admin/page.php?action=edit&post=<?php the_ID(); ?>">
       <img src="<?php bloginfo('stylesheet_directory'); ?>/icons/page_edit.png" title="Edit this page"></a>

Well, WordPress logged me out for some reason, but I had the site still opened. Refreshing the page forced me to login again and that did the trick.

No, this is not related to the plugin, but rather to WordPress. I just want to delete the normal spam comments.
But this function, as pointed out by mrmist, is not there! I have WordPress 2.6, but when I go to the comments menu, there is no filter, no spam category, nothing! I was annoyed because of that earlier, but thought that’s normal.

Is this a problem with my WordPress version, or am I just too stupid to find it?

After reading the FAQ, I found out that it’s normal that reCAPTCHA marks all comments with wrong word combination entered as spam and keeps them. That explains why I got 8400 spam comments.

But I still don’t know how to delete them from the admin panel!
