I have three moonkins at 80 and have learned a great deal about multiboxing in the process. Based on that I wouldn't consider many of my questions to be "new MBs."
However, I'm venturing into 5-boxing territory and with that many of my questions may be considered (by some) "new MBs."

Is the New MB forum for those just starting out on their MB journey and don't know much about anything or is it for the rather basic questions that anyone with that certain playing style could answer?
