Sim Restart Notifyer

When the region (with object that runs this script) restarts, the script sends all registered residents an instant message telling the sim is online and what channel and version the sim is now. It also displays how many restarts the sim had since the script itself was restarted.

This is practical when you want to know when you can return to your sim and continue working on your projects. Registered residents do not be online — when IM-to-mail service is activated for their account, they will receive the notification via email.

Usage

Create an object or use any created already as container for the script. Put the script into. In this case you only will receive restart reports. When you want register other residents, or your partner or alts as message recipient (please ask if they want to), create a notecard and fill it with names or keys, one key a line.

For example:

# Put the keys of the recipients or the names here.
#
# Using keys is more effective — names need resolving!
# You can combine keys and names by using a comment,
# like this:
#
eb66b7b7-7ddb-4c5a-95ad-bfeb9837ae29 # Jenna Felton
#
# Less effective but also possible:
Jenna Felton

Each key and name must go in a different line. You can give the notecard any name. Then put it into the container and reset the script. After it reads the keys and resolves the avatar names, the script is ready.

The script writes as floating text the current sim version and restart counts. By clicking the prim, the script also whispers the restart report without sending it to other recipients (no provoked IM spam).
