wiki licensing

we (the web team) are doing some hacking in the chapter registration 
script.  when it's finished, there will be magic.

and we were thinking about wiki licensing for chapters.  we looked at 
national because we figured we should just emulate the licensing at 
wiki.freeculture.org.  but now we're not so sure.  wiki.freeculture.org 
is using the GFDL.  with wikipedia's recent move to cc-by-sa, perhaps 
SFC should follow suit?  or perhaps people would rather we use cc-by 
(less restrictions on use, but doesn't assert the copyleft)?

thoughts?

me first:
we should go with cc-by-sa.
