I have brushed up my CommentBox solution to use REST queries instead of the old web-service queries. I have rewritten the entire solution and brushed up most of the functionality.
What is this solution
You can add a CommentBox to any page in your SharePoint site to enable the users to post comments and discuss topics. You can have rich text or plain text comments with attachments, and multi level replies. It has paging and subscription to comments by email.
Please note that the new version only supports SP 2013 and above. If you use SP 2010 or SP 2007 you must stick with the old version.
Check it out and let me know if you have any questions.
