Development of Creative Commons licenses

[Patrick Crosby <pcrosbynet AT gmail.com>]

I have a question about the non-commercial cc license:

Say someone created a community website where the users contributed
content (i.e. a wiki), and when they submitted the content it was
clear that the content would be licensed under a creative commons
license that has non-commercial in it.

Does the owner of the website have the right to make money off the
content (through ad revenue, for example), or is the website itself a
"user" and subject to the non-commercial portion of the license that
the user contributed the content under?

I understand that the creator of work licensed with a CC
non-commercial license can make money off of it, but in this case, the
creator/owner of the website would be making money, not the creators
of the content.

thanks...
