Please feel free to send in new plugins to collectd's mailing list at
-E<lt>collectdE<nbsp>atE<nbsp>verplant.orgE<gt> for review and, possibly,
+E<lt>collectdE<nbsp>atE<nbsp>collectd.orgE<gt> for review and, possibly,
inclusion in the main distribution. In the latter case, we will take care of
keeping the plugin up to date and adapting it to new versions of collectd.
