After some browsing on Steemit i came along @frontrunner #frontrunner, To be honest, the info what you can get is very limited.. so I asked some questions on discord to @fyrstikken and he just said, try it and see it... As I am a small minnow I don't expect anything.
some info can be found here:

I will give an update in some weeks..
P.s. your voting power must be between 90% and 100% otherwise it won't work..
