Visitors can leave comments in two places on my.raceresult.com:

1. On the Reviews tab they can leave longer texts and rate the event with a 5-star-system.
2. Comments can be left for specific participants in the Participant View. 

Comments can be set in Particpant Views and the Reviews tab can be disabled if you choose. Moderation of comments can be done on the Handle Comments page. 

Note that each comment is automatically analyzed by an LLM and reviewed daily by Race Result. Comments can be classified as allow, review, or block.
