We've all seen the many and varied threads on such items as: can I use +P+ ammo, magazine safeties and so on. To avoid repetitive threads for those who can't/don't do searches, a FAQ section might save quite a bit of bandwidth.
One of the other boards I belong to has the FAQ as a completely separate, stand alone section. I didn't notice it in the revolver section, because I rarely go there. Also, it's not an intuitive choice if you don't have any interest in revolvers.
