Hi Steff,
you haven't let her find out for herself have you ? You've bulled it up to high heaven. The X-pert course is Ok for Newbies but not that great in general - Caroline is possibly well past anything they have to say.
Peter I will say this only once. I am going on the course and will find out for myself, regardless of anything Steff or anyone else says. I am going with an open mind, so please don't make assumptions on my behalf.
