Not only newbies, to be honest. Everyone keeps talking about newbies and how they break forum rules because of not knowing them or because of not paying decent attention to them. But I suppose many forget that those newbies eventually become members, full members and even higher, but they still don`t know a lot about forum policy and continue to write low quality posts even though they are not newbies any more, at least technically speaking. That is why I believe that advice for improving quality are useful for everyone despite forum rank and activity. If a person strive to learn he will always find something new to himself.
