Yeah... voting guilds are a specific new thing that will be coming out after graphene 2.0. It's not trailing votes or anything like that. Everybody jumps into a voting pool, and everybody in the voting guild/pool gets the average of that pool's Steem power. It's not something that exists currently. If one person votes on something, it doesn't vote on anyone's account except that person's. More detail will come out soon, you didn't miss anything ;)
