You may  see a guy wandering in and out  groups and that's a guy called Geoff  who works for the British National Corpus and these are the people who are trying to have or produce ten million words of the written word and a hundred million erm spoken words, which is a corpus whereby, er  come and look at the English language at some time in the future and identify and listen to some of your  and your dialects and what you said  so make sure you have lots of input as we've got quite a broad spectrum of different dialects today but he'll be wandering in and out er throughout today.
