I think the announcement has a mistake: It is Luogu Round 210 but not Luogu Round 10.

Nice contest! I had fun participating, and it was especially nice to see that the quality of translation has gone up by a lot. Some minor questions (not directly related to the contest, sorry if this is the wrong place to ask!):

• Is there a way to filter for only rated participants in the ranking page? It's not that important, but as someone used to atcoder and codeforces, I was somewhat surprised to see 2000+ rated participants in the ranking and no immediately visible way to conceal them.
• I think someone DMed me asking for the solution to a problem? I can't reply anyways due to not passing real-name authentication, but is there a way to report such messages? I couldn't immediately see it in the interface. (also, I think it might be good to add some kind of warning when messaging users who haven't passed real-name authentication. People keep DMing me even though I can't reply)

I'm looking forward to the day when Luogu offers a completely English interface alongside a Chinese one! The system currently feels somewhat clunky and awkward with the mix of Chinese and English, but it was a lot of fun nonetheless.
