You are asking about newbs, but "n00bs" is the title of this thread. Therefore, I will give you my brief opinion on both. Newbs are perfectly fine and usually become non-newbs after some time, but n00bs are unacceptable. The population growth rate of n00bs must be decreased. If the n00bs become predominent on this site, non-n00bs may have to flee and go elsewhere.
Here is a survival guide which I have found in the forums: http://www.chess.com/forum/view/general/guide-to-chess-noobs-n00bs
What are people's opinions on chess newbs?
