That votes outside of the voting period don't matter and that only the votes cast during that period are counted towards the majority. So that if there are 3 votes total and two are yes and one no it passes, or if there are a total of 9 votes and 3 are yes and 6 no then its a no. The way you have it written now is correct, but a person could mistakenly read it to mean that you need a 50%+1 majority of the entire council rather than a 50%+1 majority of the actual participating votes. I think you need to emphasise the "votes" part more.

Either way it is not a correction just more emphasis, I think we can put our stamp of approval on this and move on to the fun stuff.
