Purpose

In simplest terms, talkback allows a user (user number one) to direct the attention of another user (user number two) to a discussion on a specific talk page.

One benefit of this tool is to maintain the flow of a discussion on a single user's talk page, rather than having to switch back and forth between talk pages in order to make sense of the conversation.

Two examples of the use of this template are:

  • If you receive a message from a user, you can notify the user that you have responded to his/her message on your own talk page.
  • If you create a topic on your talk page, you can notify a user that the discussion might need his/her attention.

Usage

For example, this code:

{{Talkback|Jimbo}}

Generates:

You have new messages
You have new messages
Hello, Talkback. You have new messages at Jimbo's talk page.
You can remove this notice at any time by removing the {{Talkback}} or template.
