# Overview

In the context of a comment, all `<$mt:AuthorSOMETHING$>` function tags refer to the author of the entry or page where the comments were left. This default behavior in Movable Type (as of MT4.25) creates a situation where it is never possible to output author data for a commenter.

# Description

The CommentAuthorContext plugin creates a block tag called `<mt:CommentAuthorContext>` in which `<$mt:AuthorSOMETHING$>` function tags will refer to the author of the comment.

# Usage

1. Create a "user" CustomField. We'll use `<$mt:AuthorDataTwitter$>` for this example.
2. Place the `<mt:CommentAuthorContext>` block tag inside the `<mt:Comments>` tag block (typically in the entry or page detail template).
3. Place your "user" CustomFields inside the `<mt:CommentAuthorContext>` tag block.

Final code might look something like this:

    <mt:Comments>
        <mt:CommentAuthorContext>
            <a href="http://twitter.com/<$mt:AuthorDataTwitter$>/"><$mt:AuthorDataTwitter$></a>
        <mt:Else>
            I'm an anonymous commenter
        </mt:CommentAuthorContext>
    </mt:Comments>
