I’m working right now to make it all the user facing text configurable from the admin section. I think that can be ready soon - later this week - if it gets approval. There’s also an issue on the plugin’s github page about it: https://github.com/discourse/wp-discourse/issues/251
For now you can do something like this:
add_filter( 'gettext', 'change_notable_replies_text', 20, 3 );
function change_notable_replies_text( $translated_text, $text, $domain ) {
switch ( $translated_text ) {
// The text content you want to change.
case 'Notable Replies' :
// What you want to change that text to.
$translated_text = __( 'Our Favourite Replies', 'wp-discourse' );
break;
}
return $translated_text;
}
I can add more detail if this isn’t clear. See this for more detail about the gettext hook:
