Impressive research! Thank you so much for sharing that with us - it is so helpful, especially to someone like me who had little to no knowledge about that very subject *g* Being at work, I only read this once qiuckly, but I know I'll be back to it before long when I'll be in the quiet of my home and able to take my sweet time. Can't wait for part 2, and the list of your sources. Could you let us know which one(s) you'd recommend as an introductory reading, if there is any that would be suitable from your list? ^-^
