Development of Creative Commons licenses

Hi everybody,

Wiki-style content is often edited by a lot of users.

Say I would run a Wiki system on my server and licence all content with
CC-BY (Creative Commons, Attribution).

I now want to publish one wiki article in a newspaper. Do I have to name ALL
contributors, even if the article has been changed by dozens of users? Or is
the last one enough? Is there a licence where I don't have to name the
authors?

I searched on creativecommons.org and in the archive of this mailing list
for hints, but didn't find an answer.

Thanks for help & greetings from Bangalore, Holger
