Drupal Categories

Categories menu allows you to to classify content into categories and subcategories; You can later add content under these categories. By clicking on the category icon next to each content itemyou can view all articles under that category. This is helpful if you want to let your visitors view articles/pages with similar content, for example.

Drupal Comments

Comments - with the default installation, only users that have logged in can access/post comments. This can be changed from Administer-> Access control. The comments settings are self-explanatory and can be tuned from Administer-> Comments-> Configure. By default, registered users can post comments (they don't need to wait for moderator approvals). If you want to let anonymous users post comments, please, go to Administer-> Access control-> Comment module.
