Comment Options

This module adds bulk operations for the comment options field to the Administer Content page. Users with "bulk edit comment options" permission can use this feature to set the "comment" field on selected nodes to Read/Write, Disabled, or Read only status.

This can be useful when replacing Drupal comments with a third-party discussion module, or vice-versa.

You can use the Views Bulk Operations module to accomplish the same thing, but this module is lighter. This is also a good module to use as a starting-point for writing your own bulk operation module.
