Issue 3418 v2

Resolves issue: https://code.google.com/p/otwarchive/issues/detail?id=3418

Version .02 now includes tests!
Yay tests! But watch me being persnickety. >.>
I would prefer if this variable was named `moderated_collections`, because it's an array, and it can theoretically contain several collections. Also, while you're in there, would you please add a space between the = and the []?
