I’m not sure, but I’ll ask someone who knows to respond. (Though looks like you managed to delete a comment below, so maybe you figured it out?)
I think another thing you could do is message the author (go to their profile page and then click “message”), but I think that commenting is also fine. Pointing out typos is an act of community service, so I think that people will be OK with you leaving the comment up!
