Sorry, if that was answered before...
I voted yesterday in the morning via AE and in the evening I bought some more Token on AE

Must I vote again with the higher number of stakes in my account?
And is there already a way to vote via bter (there I have some more...)?
your vote will be weighted by the amount of TOKEN you have at the closing of voting
no need to vote again on AE, but if you also have TOKEN on bter, then yes you would need to vote there
still waiting on bter URL
