I have a profile page and I need to make a comment system on it. The comments system should work exactly the same way as standard WordPress comment system, but instead of posts it should work with users. For better understanding, I have 1 page which acts as a profile for every user (user_login is in the URL) and at the bottom of that page users can leave comments about ‘profile’ user.
Any ideas how to achieve this? What should be changed? Is there any wordpress plugin for this of can you send me any PHP function for this.
