There is also a mechanism for sharing curation rewards with delegators (not that that would be my main reason for doing it), @friendlymoose knows the secret sign (code)
There are probably more, but I'm using the Hivediscomod service to return an adjustable amount of the curation rewards (for @topcomment I use 80%) in liquid Hive to the delegators on a daily basis.
Thanks @friendlymoose. Never has your name seemed more appropriate!
Haha. You're welcome!
