The version number WP shows on
is 2011.0920.2011 that makes it seem like it hasn't been updated since 2011 but it seems some updates were made just 2 weeks ago. Having that number show 2012... might help people.
It also might be nice to let people set the minutes as a variable. In case they only need it to check even 100 minutes, or something, instead of every 5.
