The atk-framework.com domain was transferred to Sintattica by iBuildings http://www.atk-framework.com/

They gave us the sources of two historically valuable resources for ATK: the forum and the Wiki.
So we've managed to move them respectively to:
http://atk-framework.com/wiki/ and http://atk-framework.com/forum/
