::::: Been following this a little bit to see how it worked out.  Anyway is that attribution page sufficient?  The standard disclaimer when you edit states "You agree that a hyperlink or URL is sufficient attribution under the Creative Commons license" but that attribution list contains neither so could we still be breaking the licensing terms for those contributions and possibly leaving us in trouble with the contributors?  Probably a more general concern than just this instance as I've seen it done before but I thought I'd ask here first as it's relevant.
