Here is a question that just came up:  My Dio has three kits, Godzilla, King Gidrah, and a Castle.  I took a photo and entered all three kits at once.  Now here is my question:  After doing some research, one of my other Castle kits would be a better match for this Dio.  Can I swap them out?  I have not started work on either kit and don't mind taking photos as proof of this.  If I can't swap them, then I will use the kit I entered with the other two.
