Well, that worked rather better than expected. Hurrah! Just to expand on my profile, I spend vast quantities of time each day stuck in a darkened room doing spectroscopy, even though the weather outside is lovely, and I am going to completely lose it if I don't have some sort of out let for all that rage and agression. Could this be it? Who knows? I'll keep you posted. I'm going to stay anonymous for a while but might reconsider in a couple of months...
