On first announcement the site was announced to be in closed beta stage, with codes given out by clicking on the invite form. Selected accounts could then send out 10 invites. TJ later added a notification option which, after users entered their email adress, would notify them as soon as Dino Cave invitations would be available. The notification option also mentioned that if users enter their Dragon Cave e-mail they would receive their invitation sooner and would be given priority access.
