I remember doing this - would have been great fun if I hadn't had freshers flu the whole time. I spent the entire few days either in lectures, or in bed. Wasn't a great experience - but I'm sure that won't happen to any of you!
I signed up to help out this time. When the CUSU access officer came to do the CRB check stuff he was pretty excited that I was doing it and I had done it previously (if you see what I mean.) He also said I was pretty much guaranteed to get a shadow, because they gets lots of people applying to do maths - but not many mathmos actually sign up to help out haha.
Anyway, if you are a Shadow, what sort of things would you want to do in the evening - or when you're not busy during the day. AFAIK you have some planned activities - but I'd be interested whether you'd like to see the city - check out college rooms - check out other colleges etc... I'd like to know, I wouldn't know what to organise.
