That's an interesting idea, but as FluteFlue implies, if part of our role on here is to demystify things/clear up misunderstandings then I doubt everyone would be as helpful as to post them neatly in our thread. (We do actually have a CompSci Oxford thread.) Although I'm not a tutor there are various Oxford tutors floating around on TSR - I think it's their ability to drop in to conversations and clarify things that makes their presence really useful.
Dvdhsu: good call on the panoramas. I'd forgotten about them. Now added as a link on the CompSci "Choose a college" web page. I think if we do it, it will be something other than just recording the existing day. (There's a lot of pressure on people involved as it is - I don't want to make that worse. And yes it does get more complicated around getting release forms if from people incase they're caught on camera and recognisable.)
Fluteflute: That's a thought. I'll certainly bear that in mind. (Which I've just clearly failed to adhere to by posting 6mins later :-) )
