Two things and i'll make this easy and simple for everyone to rake in some high Cast Point rewards.
Post an ad on a site that currently has no ad for this site and earn an easy 100 Cast Points upon providing proof.
If someone registers to the site and mentions your name in the introductions forum with mentioning you brought them here you, BAM, get another 200 Cast Points just like that.
So bring those people, rake in the Cast, and Deadman Wonderland will soon be a full prison.
