CameraSynch2

CameraSynch2 v1.0.0

Synchronization of multiple avatar cameras.
This script initially needs to be dropped individually into numerous linked prims.
However because the script adds a PIN, after its been added once the owner can issue the "update" command to automatically propogate any changes made to the root script into the child prims/scripts.

TO USE:
1] Rez a bunch of prims, one for each bum you want to sit on them.
2] Link them together.
3] Drop a copy of this script in each prim.
4] Sit one person on the controller seat, and some persons on the other seats.
5] Read the spam when you sit down.
