As it stands with only 5-6 people and a total of 19-21 sets, anyone signing up for more than 3 sets will receive duplicate blocks as there won't be enough different blocks to go around. I really don't care to receive duplicates. So, if there are not enough signed up by the deadline for at least 30 sets, I will probably withdraw also. But I'll wait until the sign up deadline to make a final decision. Maybe more will sign up.
