Continuity and (un)Originality: appropriating stubs of projects and taking them forward

In looking around for more about the exhibition on reproductive health representations by women,I found a website titled the Groundswell collective LINKED HERE. There is a link from 2009 to a project called Imagine Peace, but all I can find online is more of the same stub. What happened to the project? Sometimes people abandon them, or groups break up, or they never get around to posting, or they are co-opted by opportunities to exhibit in more private spheres: (such as the gallery or museum). Nice idea; what happened to the project? Why not pick up stubs of other abandoned projects and reproduce them?
