No need - I've moved it for you
Once upon a time Rolo was talking about getting a few folk together for a trip to Scotland. I will poke him next time I see him.
I think that, unless you know the organiser, or someone who has been on a particular course before, it's very difficult to judge the level at which the course is pitched. I would hate to put up several hundred pounds to find that the rest of the course members were at the "this is what the aperture ring is for" stage...
