I would love to see the diesel pool (or multiple diesel pools) for POB. I would even throw 100 BEE in for the cause. Let me know if you want to take me up on that.
I also think buying POB from the market and using it as a reward/award would be useful. Good for the market, good for the community.
Getting hivelist to accept POB and getting a store up and running is awesome. This bodes very well for things moving forward.
