As I post this question there is no notice that my content is being released under Creative Commons licensing. It looks like previously there have been modfications to it Are the SE additions to the Creative Commons attribution requirements enforceable? But I don't find anything about it being completely removed.
I noticed it on Pets.se and it seems to be missing on all sites beta and graduated.
Where are the creative commons notices?
As pointed out by Journeyman Geek in the answer below there is difficult to see notice that user content is licensed under CC, but there is no notice to the users posting content that they are releasing content under CC. We used to have a fairly obvious notice when posting, much like Wikipedia still does.
There is a requirement that users be notified that content is being released.
CC alerts prospective licensors they need to have all necessary rights before applying a CC license to a work. If that is not the case and someone has marked your work with a CC license without your authorization, you should contact that person and tell them to remove the license from your work. You may also wish to contact a lawyer. Creative Commons is not a law firm and cannot represent you or give you legal advice, but there are lawyers who have identified themselves as interested in representing people in CC-related matters.
So my question remains where is the notice that tells users they are publishing under CC?
