Part of a wider update, you can now @TXTWRK:Define your topic! like starting with ':' and ending with '!', allowing you to tag your topics across the platform.

As of today, you can also imply TXTWRK.com/@Username:TopicName! as a shareable link, whereas the space TXTWRK.com/@Username:Topic Name! between the topic words can be implied via address bar input.
