Organize purchasers at 250 West Street

I am a purchaser of a unit at 250 West Street. I know we have rights under our contracts but I'd like to try to organize some of the purchasers to discuss Hurricane Sandy and make sure the Sponsor is taking appropriate steps as it repairs the damaged basement. The Cantor Pecorella folks are friendly and now being responsive but I feel the process is far from transparent. We can leverage our strenght together. Please comment on this discussion if you are a purchaser or have any ideas on how I may connect with other purchasers. I don't want to wait until things go wrong (after closings) to try to organize after the sponsor has taken its money. . .
