Starting Mere Christianity next week

Starting on next Thursday, I'll be going through Mere Christianity. The book is broken into 4 parts, so I'll spend the first 2 weeks on the first part, then probably moving to part 2 for two weeks, and so on for 8 weeks. I will be doing more commentary than summary (I hope) on the writings, so it may be a bit confusing for anyone who hasn't read the section I'm currently talking about.
