 * I got this message after installing:
 * > The plugin generated 1095 characters of unexpected output during activation.
   > If you notice “headers already sent” messages, problems with syndication feeds
   > or other issues, try deactivating or removing this plugin.
 * Any ideas what this means?

 * The plugin you activated may cause problems with your feed files. Have you checked/
   validated your feeds since activating the plugin?

 * Doesn’t seem to have any effect — [http://wanderingpoet.com/?feed=rss](http://wanderingpoet.com/?feed=rss)
 * This is a fairly fresh WP installation, using the Thesis theme. I just activated
   the plugin, but am not yet using it.
