So I got a letter a day or so addressed to Dear Clarion West Participant. It was a flyer for this year's workshop, and it asked me to pass it along to anyone I thought might benefit.
I think they got me on the wrong mailing list by accident. Unless I slept through six pretty intense weeks last year. That would be one hell of a blackout - the sort of thing I've always been afraid would happen to me, but one which I was reasonably sure wouldn't actually occur.
