  ==clean-up: any preferences?==  This article needs a bit of a clean up as noted by Kjd and anon poster. There are a number of duplications but, more importantly, why do we have both a list and a table? Surely it's much better to have just one. I'd go for the list, I'll change it all soon (when I get a chance, do it yourself if you fancy it). Anyone any preferences for how to format it?
