Welcome madurotom --- the term 'newbie' refers to someone new to a forum, not necessarily someone new to cigars ... and after a year here, that drops off. Over at CF you are considered a newbie until you pass the two year mark!
Also, tunneling can occur from improper lighting, or if the wrapper is moist and the filler & binder are too dry. You will also notice a sudden harshness to the smoke. To prevent tunneling, be sure the wrapper is properly lit and the cigar is producing ash evenly across the entire foot.
Try doing a few 'search the boards' with a different combination of key words, or just one word. Many of the topics that those new to CB like to ask about have often been discussed here hundreds of times, and you will find a lot of great info ...
