I have an interesting Halloween Event Idea that I saw through another forum (as a fan art). How bout carving a real pumpkin - related to any of the MMOG featured games, taking a pic, and voting before Halloween?
Prize? Maybe an orange event badge (not banner, but small collectible badges) and a subscription somewhere. Neko, if you like the idea, I'll help pay for the event - but I'll also be entering the contest
