This service is free for any group member to use. If you use it, please post a comment here so we can see some of the great ideas you come up with!

Instructions and code after the break.

How to use it:

If you pass it a valid group key, it will return the group name, as found in SL search. If the group is not listed – either because it is not set to show in search, or the group key isn’t right, it returns an X.

The URL to check the name is:

http:/groupname.scriptacedemy.org/MY_GROUP_KEY – where “MY_GROUP_KEY” is the SL UUID of the group.

Here is an example script to show how it could be used:
