There will be new website soon. The season starts in December with some changes in rules. The absence of opencup-ready problemsets except for Petrozavodsk summer was one of reason of the too start (i was not ready to run 2-3 GP and then wait 3 months). Another reason — some things needed to be sorted out, for example, it is related to simplifying the eligibility rules between the GP (matching of the all teams of the big camp as the main event was the real hell). For example:

1. The communications will be moved into Telegram.

2. There will be two servers (for those who do not want to use the Yandex one by some objective reasons; however, those who are OK with it can stay there). As soon as the solution with the second server appears, the wide announce of the season will be posted. The existing logins will be regenerated totally for the compatibility.

3. The team from the onsite is counted as participating in GP ONLY if it added the opencup id/login (like seoul05 or karelia14) in the team name or used the SAME opencup login (atleast for the camps on Yandex or ejudge-opentrains it can easily be implemented at the registration time; useful part of it — the opencup team does not need to memorize their new temporary-camp-login). For competitions where this feature is impossible the organizers may collect and provide the opencup logins list, like one that was used at Pottosin's Olympiad).

...and some more.

You can upsolve them on Baekjoon Online Judge. (I am unsure on how early they upload new tasks, but they do upload them asap)
