Lighting in the virtual world

Image
 Several months ago I decided to go to a disco and because there were so many people the lag was unbearable. So I kept my graphics to a minimum. When I returned to my virtual home, I forgot to put the graphic configuration as I had previously. I noticed something very strange, it was totally dark but the lights were not on. One of the most basic scripts that can be done is to detect when it is night or day.

I have recently observed that my automated greeter is not working properly when click the option to list the last 100 visitors. It only shows the first 64 in the list, then it stops. At first I did not know how to diagnose what was happening. The scrip
