Thanks! YOu guys rock with your help.
I read them, and then recklessly decided to ignore it all and plunge ahead with level 2 science, level 2 leadership, and level 2 medicine.... because I am that way ;-) . I seem to be ok as I am eeking by with +- 1000 food, raindancing for mushrooms and more fruit, and am 6000 away tonight from getting that fishing...
I am only sad that after this game I'll be finished. I love these games! Looking forward to VV4....
