There seem to be comment boxes on the home page and about page. Will need to find out how to disable these.
Update: 4/25/12 – set the default Settings->Discussion setting to not allow any comments, then for each page did this:
!. copy it to a new page created with the new default options.
2. update the menus deleting the old version from it and adding the new version.
3. Deleted the old version of the page.
Voila! no more comment boxes any any pages other than this one!
