Something that I've pointed out before: the wording in the pre CT 1.0 
"contributor terms" was very fuzzy, in particular it -did- not clearly 
state that you were licensing the data to "the operator of the website" 
on CC-by-SA 2.0 terms, it could just as good be interpreted as giving 
"the operator of the website" permission to license and distribute the 
data on CC-by-SA 2.0 terms, leaving the internal contractual and licence 
relationship open.
