I just noticed a substantial increase in the number of MPQDraft downloads over the past couple months. It took me a second to realize the likely cause: SC2 going into beta mid-February. It's not clear to me whether people expect MPQDraft to work with SC2, or whether SC2 has inspired a more general revival in modding.
In any case - MPQDraft does not work with the SC2 beta. For an explanation of why this is, and whether that may change in the future, see my blog at http://qstuff.blogspot.com/2010/04/mpqdraft-and-starcraft-2.html
