Something that causes never ending pain O.o
Just kidding, Jasper when someone is 'active' it means that they are always busy or engaged in something or with something. In this case it is with something: "Are you an active member?" = "Are you a busy member?"
Furthermore active is an adjective not a noun so saying "What is an active?" is like referring it to a being (like a person). Correction "What is active?" or "What does active mean?"
---Status: "I'm betting everything on it!"---
Fun Fact: I actually dislike cats :]
Well, I'm new here so I guess I'm somewhat active?
