Thanks. That sounds like great advice.
I was wondering about this one and had put it to one side until I had a chance
to look at the memory implications in more detail. We run a VM infrastructure
here, so I'll load it up on one server and keep throwing resources at it until
I have something approaching stability.
An almost related item ... have you found the 'RelayCountry' plugin to be worth
the effort?
Thanks again
