Fencer: Does the 'new' brainking kick in automatically when the 'original' brainking is getting full?

I was thinking (always dangerous) that if members were to use the 'new' one and pawns were to use the 'old' one, would that help lighten the load, or more evenly distribute the traffic. A link to the 'new' bk could then be put on the 'members only' board.

I know, I know.... I admit it! I haven't a clue about computers and servers and stuff.
