The fact is it's not actually necessary just like a majority of other users and also said. Basically any post that falls under the guide category will 90% of the time fit in the beginners and helpful board which actually makes a whole lot of sense considering it's created in the first place to help user (mustn't be a newbie).
It's high time users understood that too many sub boards is also bad for the forum. The more sub boards that aren't necessary the more inactive more boards become.
