So some threads have like a flame which indicates that they're 'hot'? While others don't. So what makes a thread hot opposed to not? I thought it must be number of replies, but it doesn't seem to be, there's a 'hot' thread with like 3 replies and a 'not hot' thread with 6. What's the secret? I would hate to make a thread that isn't sufficiently hot. How embarrassing!
