Margin Requirement Change Alerts

I was digging around CME's website but wasn't exactly sure where to find this.

I am looking for an Email or Alert that will tell me when CL, TF,ES,GC,SI,NQ,YM Margin Requirements change takes place.

Could anyone point me to the correct site/link that would be the first to be notified about any margin requirement changes in those instruments?

Thanks,

Z

I am subscribed to the email "updates" for metals, energy, and indices already. I also follow CME on twitter, Last time gold margins changed a while back ZeroHedge caught the info like four hours earlier than CME released. Was seeing if I had the right links. Guess it was leaked or something....

Ah well ,

Thanks guys.
