You say no minimum then why are there so many not paying if your weight is down.I have like three address's that are not paying for vote But also have some that are and all address's have same amout of coins.So is the pool not to be trusted they are not paying.And also can not change    the vote on the wallet.There is no unvote as cana mentioned eirlier post to do,even ctrl+r does not take pool vote to change pool votes
