Well, the reason I didn't suggest a possible time is because I haven't got a clue when would be ok for me. I don't know anything much about next year other than for two weeks "in summer" I have to be on a dig. So, to my knowledge, times that are ok for me are any weekend other than 2 of the weeks in summer but I can't actually say which weeks those are.
As for location, all I can say really is someplace in London, basically because its pretty easy to access from anywhere in the UK (trains and plains are dead cheap if you book in advance). I can't say anything more specific than that because I don't know anything about London other than that its that city sort of place that I think is over there *points*.
Anyway, I'll pester a load of lecturers until one of them gives in and tells me what he/she knows about next year, then I'll suggest a time. Ok?
(Honestly, is it really beyond anyone here to have a suggestion of their own which isn't an attempt to shoot down the whole idea?)
