Special rewards will come to those who manage to collect all 7 sin cards and present them at the "Party":http://revjim.net/item/10206/ on New Year's Eve. These come in tangible paper form, as well as online versions that you can print at home. Weeee!
Here is one of many. Print this out (as it not guaranteed to stay here for long) and be on the look out for more posted here, as well as in other places about the many, many internets (yeah… this place is big, so I might give you hints along the way).

This party is going to be a blast. The Gods and Goddesses of party planning just announced a few new events for the party. I won't spoil all the fun but I will name a few to keep you interested: a *John Wilkes kissing Booth* and a *twinkie sucking contest*.
Enjoy!
