The free sites are actually hosted by Community Architecture --> http://www.communityarchitect.com/
Unfortunately we had to detach ourselves from the system because some low life individuals where using the sites to spam, phish for information, and other unacceptable practices. And with our name attached to those sites it appeared we where doing the dirty work.
Anyway you can contact Community Architecture directly to get your site fired up again.
Sorry for the inconvenience.
