There has been a rash of people digging up old threads lately to ask questions about them. If the thread is over 6 months old, and you have a question, send a private message to the original poster of the thread. Nobody else wants to see the thread pop up as a new post. Many people are posting questions about products that were listed for sale years ago or the original poster is no longer an active member. If their notifications are set right, they will get an email telling them they have a message. If they are not active, they will never know you asked a question.
A leader without followers is just a guy taking a walk.
