Card Production, and a question. Thanks!

Received Card Production emails today (02/04/2014) for myself (primary applicant) and my wife.

For time reference: TSC, EB2, PD: 2008 Dec.

Changed job and state last year, but no RFE :-)

Appreciate all nice help offered here!

Bless all who are applying/waiting for green cards!

A quick question:

We filed address change online last year. We received hard-copy letter from USCIS acknowledging our new address, but did not receive USCIS email update on our new address. Is this a concern? (I don't think so, but wanted to hear your opinions). Thanks!
