Hi Jethro,

That's wicked. I've seen the references to using "this" in the docs
before but it didn't quite sink in about how to use it. Your config has
made all the pieces of the jigsaw fit and I'm all up and running now,
and my config is about half as complicated to boot :-)


Many thanks for your help.

Cheers,

Dunc
