This is just a short message to say thanks for the discussion, guys. Unfortunately, my university workload is beginning to hot up and I simply don't have time to participate in this list in the manner that I wish and that would do me credit. Consequently, I'm going to have to sign off, for the moment - but thanks for the stimulus, nonetheless.

Au revoir,
James Hughes.
