@ComicMan24: IIRC, it was the Dead-Head one and again, IIRC, it was the only one. There are ones that you get the extra experience for if the allotted number of people complete them, but there are some that are only available for a short time.
nice to see this thing is still going. i haven't attempted to follow these since coming back from vacation due to slow connections forcing me to be selective about what pages i load.
though i have gone up two levels without even trying, the second level achieved by completing four quests at once just by posting the usual random thing in the Whats Going Through Your Mind...thread. odd indeed.
@Captain Cascader: May I suggest a new quest idea? Do one focusing on.....macguffins! People will have to search the database for 10 of the most famous macguffins in comicdom and cartoondom (and that includes a few items from GI Joe and Transformers, such as the Dragonfire energy from Operation: Dragonfire, or the Key to Vector Sigma).
