 * Thank you for writing this plugin. I installed it at my WordPress multisite, 
   and after that, when I visit a network site’s dashboard (as admin), I get several
   PHP warnings that begin with “Warning: Cannot modify header information – headers
   already sent by (output started at …” In addition, in the Tools menu there’s 
   no “Delete Comments” option.
 * The FIRST PHP warning starts with: Deprecated: has_cap was called with an argument
   that is deprecated since version 2.0.0! Usage of user levels is deprecated. Use
   capabilities instead.
 * If I visit the dashboard of a network site that has no comments, then I don’t
   see the PHP errors.
 * I have five comments, and I get five of the “headers” PHP warnings, so I’m guessing
   the plugin’s checking over the comments and throwing an error for each one.
 * The reason I want to use your plugin is, suddenly I have 20,000+ comments, yet
   in PhpMyAdmin I can see only five comments in the wp_3_comments table.
 * I’ve since restricted comments to only logged in users.
 * Thanks in advance,
    Carol Mattsson
