I have noticed multiple times in this forum people using the term n00b or noob and even using it on themselves or using in titles and such. I personally feel there is a difference between the two spellings. n00b to me is an anoying gnat that goes around the forum being a pain in the butt lol and doesn't want to learn anything. A newb is someone new to something but is willing to learn.
This here is a good article that I find relevent and explains it well lol.
This is just a personal opinion on the matter so peeps don't go all haywire lol
