Hey i have another suggestion to add :p
Once we Post a publication, we don't have any chance to convert it to 100% powerup.
There is a possibility that people will do power-up posts and then after getting a big vote they switch back to 50/50.
But there can be a thing to only change the rewards to 100% powerup if they were not. If they were set to 100%, you can not change that back. Please count this too :p
Yours, @haidermehdi.
