Update node from comment form Is there a way in drupal 7 where you can change a value of a field from the comment form of that node you are commenting on? At the moment I have a comment form within a node which has the same field as that node. When I change that value, it does not update the nodes field but only changes the comment form's field. 

Thanks for your help in advance!
I wrote a module to do this, you can probably modify it to suit your needs. http://drupal.org/sandbox/jrowny/1281972 I was using this for 'casetracker' type functionality. 

Basically you install this and check for each field "this field is editable by comments."
