I saw your question for Glen when I was talking to her (no, I am not stalking you!). The addiction threads can be explained as more of a "When do you know you are addicted to Narniafans" list. We try to offer a thousand symptoms of our addictions, such as "(you know you're addicted when) you say 10thingy in real live conversations." We're counting down from 1,000, and our aim is to get to 0.
Here's the original thread, which got too big and was therefore moved to Cair Paravel when they revamped the forums.
There are two second threads, because holyboy the mod started a continuation, then forget he had done so and started a second continuation.
