This script can do two things: It will make a list of all that Touch it, except the owner, and it can Instant Message owner the name of each person Touching as it happens... 


What it cannot do is add people to a group. Unfortunately, that is not yet available in LSL as of now (JAN 2007.)

A good way to use this script is to place it inside of a sign like I have at my store. Check it once or twice a day, reseting the list after getting the current names and adding them manually to group.

IMPORTANT: You must Reset the List before it gets to around 125 or the script will stop working.
