Using the #comment-id and @username tags, wpDiscuz User and Comment Mentioning enables the mention of specific comments and users in comment content. It has a user search box, making it simple to locate and tag any user or visitor.
Each comment’s #ID is also shown, allowing you to tag it. Email notifications will be sent to all users listed and comment writers.
This add-on converts links with avatars to replace @author and #comment-id. When you mouse over the @author and #comment-id links, a pop-up box with user and comment details appears. Please be aware that this addon requires the Comment Rich Editor to be activated.
