Content for wikias is licensed under the CC-BY-SA 3.0  (Unported). You could in a sense individually waive the attribution requirement for your specifc contributions, but this would amount to a statement by you that you would not pursue infringements, and not a default status of the community itself. The opposite would not work, in that you can never impose terms more restrictive than the  CC-BY-SA.
