The points have disappeared because Polarkernel was now successful in nullifying the meta points.
If I remember this correctly, we agreed upon setting the requierments for voting and commenting to "Registered users" until we go publicely online, such that everybody can express his opinion about the ongoing discussions by voting during the technical private beta.
The settings for the voting privileges are already set in accordance with the public mode of PhysicsOverflow. As Dimension10 has recorded them in the appropriate part of the the FAQ, I'm going to change them back to the technical private beta mode for now, such that you and others can still vote.
