The tpl:CommentIfMe tag returns a value if the comment is written by the post author, in a tpl:Comments loop context. To determine if the comment author and the post author are the same person, the tag tests that:

• the comment author's e-mail address is the same as the post author's e-mail address (the one set up in his user profile)
• and the comment author's website URL is the same as the post author's website URL (the one set up in his user profile).

This attribute defines what value will be returned in case of success.

• return="me" will display me only if the comment is written by the author of the post.

<p{{tpl:CommentIfMe return=" class=\"me\""}}> ... </p>

In this example, the comment will have an extra CSS class me if its author is the same as the post author; this CSS class will allow a special design for it.
