Ken Jenks' AD&D1 House Rules

From the introduction: In a fit of egotism, I've just decided that the whole world needs to know the house rules I use in my AD&D1 campaign. At the end, as a reward for those of you who either read through the whole thing or search for the word "ERRATA," is a set of corrections for DMG1 and PHB1. I am ready, willing and able to defend each rule. Enjoy, comment, use and abuse at will.
