A page of Arianism: http://www.scoop.it/t/arianism
A page on Digital Ancient History: http://www.scoop.it/t/digital-ancient-history
A page on Early Christianity: http://www.scoop.it/t/early-christianity-by-kevin-kaatz
and a page on Manichaeism: http://www.scoop.it/t/manichaeism
I'll definitely have my students create their own Scoop.it! pages so that they can see what others are doing in their favorite history topics.
