From all that I have read herein and found on WordPress, it seems that there is no way of removing selected page or post comment capabilities, nor to remove all comment capabilities, nor limit the ability of anyone to read and edit any comment that is made.
It would therefore seem that WordPress is not well suited for website development as boasted. Otherwise I like WordPress (just as I do Wix, which has it's own fault issues).
Open Source contributors has done a great job in spite of these short comings.
Any suggestions would be more than welcomed by many who have presented this question in several threads.
Maybe "Christine Rondeau" may have a solution...please.
