What is the best way to put comments section to user profile I need add ability to add comment for user profile. What i am thinking is, create a content type with empty body and leave just comments, and afterwards insert that node to user_profile.
But i don't know how to append comments to user profile tpl file. How to do this, or maybe other suggestions?


  After some research i decided to make my own module to add comments on
  user profile, i will make a block and insert this block to only user
  page user/*, and will track user id to show proper comments.
If you use Profile2, this creates profiles as node type entities so you can turn comments on as each profile will have settings similar to that when you create content types.
