If ever they will run another campaign here on the forum, it's great if they'll be able to hire one of the best campaign managers out there. But even if it will be the same campaign manager as last time or any good manager out there, I think there should be any issue about that as the main issue last time was not the management rather it's the payment. Still, Escrow for the payment should be made to avoid the mistake that happened before.
The problem last time is delay of payments so I think they really need to fix this since its really much causing trouble to them since many people get curious if they starting to get a problem and maybe even think that they are shutting off. But since they are much doing good right now I guess its better to have good manager which can be trusted as an escrow also so that they can avoid the same mistake again and they can also run a campaign without encountering any problem.
That's the thing, the problem with their signature campaign was not in management but rather it's the delay in payment, in short, what they need right now to run an effective campaign is an escrow to avoid any future issues. Also, If I am correct the previous campaign manager is a solid one already and one of the best campaign managers out there so in any case, they don't need to change any part of their team and just continue the previous campaign.
