well, on a serious note....
As I was making a few comments in galleries today an idea struck me (left a sizeable bump on my head too)
Some of us could add a copy and paste paste comment in addition to regular comments, to promote the critique group, saying something to the effect:

" Note to all: If you wish to participate in a productive discussion about how to improve artistic and technical abilities while discussing your own and other people's images, please visit the new 'critique forum': http://www.renderosity.com/mod/forumpro/showforum.php?forum_id=12474 "
