Hi. I see no event related to a split topic (when moving some messages to a new or an existing topic). The only event fired is the created moderation message. It seems that we have no way to know from which topics the messages were moved from and to, as well as the list of the concerned messages. Is there a way to know these information, and if not, is it planned? ---

It’s mostly because we haven’t needed it yet. Why do you need that event? ---

Hi, I’m working on my own comments system between WP and Discourse (with the help of [WP Discourse](https://github.com/discourse/wp-discourse)), and that’s the only action that lacks an event in order to be aware of a topic replies changes on Discourse. ---
