Template:Ping
@Someone:
Instructions
This template takes advantage of the new mention notification to ping the person you are replying to in a discussion (so you don't have to use the {{talkback}} template). Right now it works on any talk page, and will soon work on Wikipedia namespace pages as well.
To use it, just add something like...
{{replyto|Someone}} Hey, that's a good point! ~~~~
...in an existing discussion. Replace 'Someone' with the name of the user you are replying to. (The comment must be signed and belong to a section.)
You can also substitute the template, if preferred:
{{subst:replyto|Someone}} Hey, that's a good point! ~~~~
