I haven't figured out how to auto yet; mine is strictly manual. I don't like leaving my voting power sitting at 100%, so I try to stay on top of it. We all know that life happens, so it's hard to stay on top of it all of the time. I hope to figure out how to set up the auto, but I'm not completely sure if I would want to auto vote all the time. I like being able to go over others' content, and up-vote what I also think is worthy. As of late, I'm definitely taking an initiative to interact more with others' and slowly build my little account up.
Thanks for your post!
Glad you liked my post! For all my contemplation, I pretty much do what you describe most of the time, too. I had set things up so I'd start following @curie's trail if my VP was above 95%, but really, it's pretty rare for that to happen, since I log on several times a day and upvote things anyway.
Interacting with other people is a great way to build your account and reputation, and something I need to do more of!
