Exclude certain roles?

Kristina,

When iterating through the roles, you could arbitrarily test for certain roles and then continue the function:

// Iterate through each role and add it as an option in the form.
    foreach($roles as $key => $value) {
        if ($value['name'] == 'Administrator') {
            continue;
        }

        echo '<input type="checkbox" class="comment-roles-checkbox" name="comment-role[]" value="' . $key . '" /> ' . $value['name'] . '<br />';
    }

I’ll go ahead and add this to the (admittedly small) roadmap for the plugin. Hopefully I can push an update here in a week or two with an options page that includes this.
