wpDiscuz User and Comment Mentioning allows to mention certain comments and users in comment text using #comment-id and @username tags. It comes with User Search bar, so you can find and tag any user/guest very easy. It also displays #ID of each comment to let you tag them. All mentioned users and comment authors will be notified via email. This addon replace @author and #comment-id to links with avatars. It opens a pop-up window with user and comment information when you hover on @author and #comment-id links. Please note, that the Comment Rich Editor must be enabled for this addon.

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.
I’m mentioning #15 comment.
