Mike is travelling for several weeks and if you want to discuss this it will have to wait until February.

regards

Hugh

NB: 

Have you read the reference manual ("doc/ref.html")?
Have you searched the mailing list archive (www.open.com.au/archives/radiator)?
Have you had a quick look on Google (www.google.com)?
Have you included a copy of your configuration file (no secrets), 
together with a trace 4 debug showing what is happening?
