Still, its the campaign managers decision on how they will give merits.
It really depends on them if they will be giving Merits or not. They always check their member's post weekly so I think it is common for them to encounter a quality post of 1 or 2.
Its also the responsibility of all the members to give merits on quality posts that they encounter daily in the forum which can also help.
That is the reason of the whole new system.
Don't just give all the responsibility to a person which they are not accountable. It will just reflecting on how you really eager to have merits over the forum.
He don't give anyone any responsibility, I think he is just pointing this out since the idea of the CMs is to check their member's post weekly and also this is just one of the suggestions you can read about the new System.
Let's say a campaign has maybe 50 participants.So the campaign manager selects the best person to post the best quality posts in that particular week and he can ask the other participants of the Campaign to merit him 1 point each.
I think the CM can do that since he can give some examples of some posts he give Merits but I think asking the participants to Merit that member is kind of a little over the top? But yeah, I think they can Merit the member without the CMs saying it right?
