Thank you for the invitation, but I'll soon be going to Illinois to spend time (including Thanksgiving) with my parents. Thus if I started as Spiderman, I would just have to drop out suddenly. I've been irritated when people did that to me in roleplaying, so I don't want to do it to others. I suggest you let Spidey be a non-player character and "reserve cavalry to the rescue" who could come to the aid of player characters if they're in a tight spot.
