@brianhphotos as far as I can tell, only the Peakd.com frontend supports this (and I could be wrong about that - I really don't know).
You can crosspost into communities you subscribe to, to share the love. Quite similar to reblogging, but with more of a built-in curation situation because a small amount of rewards from the cross-post, if it gains any, would be shared with the community and the person who shared. (The original author, i.e. you, would still get 90% of any rewards generated on the cross-post specifically.
... and that's all I know so far— I only just realized that was a thing on Peakd and Steempeak last week.
Thanks for the explanation. I've only started to use Peakd myself and think I need to find out more about communities.
