I've had an email through looking for people for potential adjudicators for this event then followed the link - https://malipivo.gitlab.io/gwr-lms/lang ... ex-en.html
I'm not sure whether they are looking for extra people to register to take part - if you're interested then drop them a message. Obviously, from the message I got they are looking for adjudicators. It also says they will aim to cover necessary expenses.
Working lists of registered players and non-playing and other participants (some people have yet to confirm their participation). My working target is at least 40 players, ideally 60 or more. That is a realistic number for breaking the record within a reasonable time.
The core of the record attempt is to solve 281 interconnected sudoku grids with a unique solution. The puzzle will be spread over approximately 39 A3 sheets laid out on tables. Solving will be done with paper and pencil, followed by entering the digits into a computer for final verification. Players may cooperate with one another. There is no time limit, but the event must not be interrupted. Players will have to solve and write down approximately 11,000 to 12,000 digits. The public event will be supervised by sudoku experts and independent observers (witnesses). Intoxicating substances, alcohol, etc. must not be used. I am not currently considering a Guinness World Records adjudicator. There is a possibility of inviting an adjudicator from Agentura Dobrý Den (Pelhřimov, Czech Records); this is currently under discussion. This depends mainly on the number of registered players.
Players must not use any computing technology that gives them advice or hints, or otherwise checks the cells they are solving. Doing so automatically disqualifies the record attempt.

This is what the enormous puzzle looks like: 39 joined A3 sheets form the letter W. The diagram shows how they fit on 13 tables, each 122 × 60 cm, available at the Katolický dům venue.
My estimate is that if each player completed one A3 sheet—an average of 281/39, or seven to eight grids—breaking the record would seem realistic with 40 participants.
