Very, very sorry yet again if these questions were answered elsewhere. Since they are no doubt obviously answered, they probably only will be asked by me.

(Edited out a question that I found the answer to)
Also, is there any way I can make the forums show me only those messages which have new posts in them?
Thanks!
P.S. I'll sneak in a third question. I've been having most of my guys work on research for the tech points. I have over 3500 for food. I've finished 5 or 6 puzzles and am now waiting for more tech points before venturing on. However, I only have 10 people, and of those 2 are children. Should I be populating more at this point since most of my adults are 50+?
