Clearly, there are certain features in Codeforces that seem to have access limits (opened for 2100+) that are not officially disclosed.
However, here is the list of features that only Div.1 people can use from my observation.
Streams — div1 people can advertise their streaming.
Uphack — div1 people can hack solution after system test.
Problem tag — div1 people can edit problem tags and possibly determine problem rating.
Catalog — div1 people can edit catalog.
Vote — div1 people vote weighted more than other.
Feel free to share if there is anything not mentioned here; there are probably a lot more.
They can see the solutions of other participants in GYMs.
nice pfp lol
A slight adjustment, streams are only accessible to those who reached 2400 at least once, same with editing the catalog if I'm not mistaken.
They have feature of touching grass after reaching 2100
Grandmasters can allow other users to do some actions (write comments, blogs, edit gyms) on behalf of themselves
Did I mistakenly hear Write solutions?
I'm Div.2 user but I can also edit problem tags (in the few days after a contest) and view others' solutions in gyms.
Div.1 people vote weighted more than me, at the same time, my votes weighted more than Div.3/4 people.
Giving more power to high rated users is really a wise move. It not only prevents the abuse of power, avoids user dissatisfaction, but also promotes academic progress.
Aren't you both Div.2 and Div.1??
