Firstly, I don't know how possible it is, I think it would be nice if every member and those joining later could join a voting trail that would be used strictly to help the community members grow, so even when we visit artists posts that are not a member yet, they could see that as a leverage and could become productive members and if we could also get a whale on the trail that would make the whole process more effective too.

They all can't win a contests but if they could at least get some sort of a community vote every now and then, I believe that could extend a sense of belonging.
