It's tragic that i no longer have access to my old account.

I want to try the unsolved problems from old account, and may be don't want to see again the solved ones.

Is there any way to find out the list of unsolved/unattempted problems (taking both codeforces_accounts into account).

I mean mark it solved, if it has been solved by atleast one account.

Thank you in advance.

Is there any update on Hello 2021?, have been waiting for it for so long.

I can see Codeforces Round #694 Div1, Div2 lined up on Jan 5, is it possible to convert this to Hello 2021 (Div1+Div2)?

I don't know much, but doesn't seem much trouble to me.

PS- I'm sorry if the announcement title makes you think it's happening.

Why unchecking the "show unofficial" checkbox doesn't filter out the unofficial participants (i.e. Participants with rating >=2100).

Even if it's intended this way only, it's a bit uneasy, should be changed.
