detecting avatar teleporting

i have an attachment that has an active script in it. some sims get kinda mad when it is running and i dont always remember it is. what i am hoping for is a short script that will let the script do a link message when ever the avatar it is attached to either teleports into another sim or logs into second life.

i know there are objects out there that do this and i have tried to ask those i know who have done it but they are trying to keep it a secret. any help would be GREATLY appreciated. i have looked into several places in the wiki and the forums (when they work) but most of the time i come up with nothing.

again any help is appreciated
thanks in avdance

The changed() event triggers when something teleports, so you can pick that up with

   changed(integer change)
   {
      if (change & CHANGED_TELEPORT) {
         do_stuff();         
      }
   }

I think that on_rez() triggers when you have an attachment still attached when you log in.

ok sweet thankies ^^ works great
