Proper attributions according to the creative commons license?

The documentation is licensed under a creative commons Attribution-ShareAlike 2.0 license. The license summary states “If supplied, you must provide the name of the creator and attribution parties”.

Since one has to be logged in on in order to edit documentation, i would assume that at least a username of each and every author is known. Which would oblige to list them somewhere.

Some pages list “guide maintainers”, however, it is not clear wether or not they are the only contributers to that particular documentation section. There are also some pages that do not list guide maintainers.

So, where can i find proper attributions for documentation?
