This plugin allows to mention WordPress users in a comment by writing usernames preceded by a character (default @), e.g. @guguweb. The mentioned users will receive a notification email with a link to the relevant post.
The mention character (default @) can be customized by a filter hook: cum-mention-char. Put the following code in your theme functions.php file:
add_filter( 'cum-mention-char', 'cum_custom_char' );
function cum_custom_char( $content ) {
return '+';
}
And the mention character will be +, so you can mention with +guguweb.
This plugin was inspired by Mention comment’s Authors by Wabeo. Many thanks to the author!
