I've been looking through the forum and I found an answer to my question here
panaghiotisadam: @peewiglet: Changing the Discussion Setting affects all posts published after the change, not already published ones. To override the setting for a single post, you deactivate the Allow Comments and Allow Pings options in the Discussion module of the post editor, or in Quick Edit (Posts>Edit > hover under post title).
I don't know where to find the Discussion module of the post editor, however. Only Discussion section found under the Settings menu.
I'm looking to disable comments on pages such as "Contact Me" and things like that. It's not necessary to do it, but I just thought I'd ask anyways in case there's a way.
Thanks very much in advance!
The blog I need help with is thingsiwanttoknow.com.
