Well you are unlimited with your commenting...you can comment without upvoting...in fact it is suggested....do not let your commenting be hindered by the amount of votes you get....
But it is good that you now have the slider bar...so you can alter how much you vote each time.
That's true, I just have to have the mindset that my comment would be worth more to all your reader's, than me not making it because of low VP. 😎
