You are correct friend, There is CENT:POB Pool at Tribaldex and we can get decent rewards adding liquidity to it. Also I think POB can match well with Cine Tribe. Already there is Cinetalkies Initiative by Hive account@gimmetricks1, to spread engagement on Cinetv and rewarding both POB and Cine. Something new with Leo Tribe can be experimented too, luckily we have a strong individual, onealfa, having strong influence in both communities. Yesterday, taskmaster4450le, gave a good suggestion on this post :

People who want to improve a community need to take it upon themselves to improve the community. That does not mean talking about it. Instead, it means getting busy.
