www.Steemvoter.com is a great one that anyone can use, crafting their own rule list, putting on accounts to vote for, what percentage voting power, and how long after a person's post comes out to vote on it.
I'm on another one run by another member, though I don't think it's publicly-open for anyone to join at this point though.
am sure there are a number of other users using custom ones as well - and could probably contract to get a custom one built via SteemChat if you wanted...
Thanks so much @rok-sivante! Appreciate the reply..Im new here and still learning about steemit. Im gonna follow you now! I have a feeling I might learn some more that way.. :)
definitely - there are some pretty good golden nuggets buried if you scroll back down my blog as well... ;-)
