At the moment, the only way to see all the Tribe members' posts would be to follow them all or watch TSU's feed: https://steemit.com/@tribesteemup/feed

As @trucklife-family said, SteemAuto is how you can set up an automated voter to follow the trail or upvote individuals. We are going to be revamping the way we structure the autovoting quite a bit over the coming weeks to implement the 1up system and maximize curation rewards, as well as really pushing the best content from the tribe!

If you make a 100% upvote (all you can do manually until you get the slider), then you only get 10x day. Most folks follow the trail with about a 10% upvote.
