Tried to subscribe to a system, got this message:  
  
  
  
_This system has been "killed" and is no longer accepting new signals. If you need help with this, please contact [admin@collective2.com](mailto:admin@collective2.com)._  
  
  
  
This system is still active, equity-curve wise. Was this system killed by the vendor or by C2???

the vendor was lucky; once APD falls below zero, the message usually reads:  
  
_This vendor has been killed and is no longer transmitting new signals_

This is done by the vendor.
