Sounds good, Rob. Sadly I'm about to move contracts so I don't know what I'll be doing in the near future, otherwise I might have been booking myself on your H&S or advanced courses. I'm bookmarking your site so I can check back when I've got my life more in order! :-)
On this theme...
If you're in Cambridge (UK) and fancy trying your hand at sound-tech stuff, the Acoustic Stage club at the Boathouse on Fridays and Saturdays will give you a chance to have a go at it. The club features a mix of individual singer-songwriters and small mostly-acoustic groups; as a beginner you'd be starting on one singer with one guitar, and work up from there. They provide all the kit, and there'll be a more experienced sound-tech keeping an eye on you and giving you advice on mic choice/placement, sound balance, EQ and other stuff.
