I checked the site that I use often so I can see how much Steem power I will be getting soon. The link I use is this: http://steem.supply/ .
I'm not the creator, but I always use this site all the time. It looks like they did an update to the site and added a little bit more stats, including the voting power.
The one who created it also added a link to vote for him as a witness. I'm not sure what that is, but I voted for him to show my support. I enjoy this site and like the new updates.
