This means that OCD will be lending some of their voting power to OCA -- basically.
In exchange for OCA being a sub-community of OCD, and for users promoting the POSH initiative, by sharing their posts on Twitter using the Steempeak URL.
The only thing I don't know how to do yet is crosspost, or why I would cross post.
Is that from one community to another?
So you could crosspost from OCA to OCD?
Yes, from any community to any other community. It also doesn’t have to be your post. You can think of it as a more powerful form of Resteem because it creates a totally new post. This solves the 7 day payout issue and allows popular content to remain evergreen.
If you crosspost other people's content you'll also receive a 5% beneficiary for connecting that content to a new set of eyeballs. It's a win win.
