Web Quests ???

Even though I've heard about Web Quests, I've never actually used one in the classroom or assigned one for enrichment ..... SO, I was wondering how many (if any) of my SURN-mates have used Web Quests. If so, any recommendations on how to use this tool in the classroom. I'm actually building one now in a class to earn recertification points. The process of putting it together is quite structured, layered, and at times, complicated.
