The enrollment provides lifetime upvotes. 5 STEEM enrollment would provide upvotes at $0.05 per week at current STEEM pricing.
New members are starting in a pool that provides only one upvote per day. As members grow their count, they can advance into pools that upvote 2 or 3 times per day.
Soon we will be releasing an automated system that will allocate value to accounts on a regular basis and then most members will receive updates on every post.
