What exactly is "vote_when_vp_reached = true" as opposed to "=false"?
That's the only box I don't quiet get, but I've been using rewarding since the Steem days and it has a hidden gem function: vote on a post after payout; I use this extensively.
To do so, comment on any post past payout:
"$rewarding 77%" or "$rewarding 77% 13min" which "creates a comment with 100% beneficiaries set to the author (of parent post/comment) and upvotes this with the given percentage and delay"
Of course you can input any vote weight % and time delay is optional.
I'll give an example on @holger80's post here.
The reward of this comment goes 100 % to the author abitcoinskeptic. This is done by setting the beneficiaries of this comment to 100 %.
'false' means if the post is created and your vp is lower than the reuired amount to follow the rule, it won't vote.
'true' means it will vote when vp recharges to the required treshold.
If you are trying to maximize curation best to set false.
If you are just wanting to vote regardless set true.
