I am trying to hide Authoring information, Revision information, Publishing options tabs in create/edit node for any content type. I tried different modules with no luck. Please give me suggestions how to achieve this. Thanks a lot
I usually do this with a custom module and drupal's Form API and setting
#access = FALSE for form elements I want to hide (and test it with 3rd party modules to assure it doesnt break anything).
Recently, I've been made aware of Override Node Options which does exactly this for Drupal 7/6.
AFAIK, Override Node Options can't disable those options, it just can enable them for users that otherwise don't have needed permissions.
There is Jammer module for removing unneeded elements from display.
