Regarding Arbitrum: I voted 1/3 for each. As the top 3 options were going to be elected, and there were only 3 candidates, unless there was a reason against it, it was a symbolic vote. In favour of the three of them!
Regarding Optimism: Same case as Arbitrum, and I also voted for the both of them.
Regarding RocketPool: Voted for dybsy, he was the only candidate and I was in favour of his position as ambassador in RP.
