I am so tired....... I have been working like a fiend to get another conference paper written up, and have just sent a draft to my supervisor to look at. I have some odds and ends to clean up in it, why do you see those as soon as you hit send? Nevertheless, it has gone, and I will leave it until tomorrow. All in all, its not bad, if I may so so. =) But I have pushed myself so hard I am now braindead and exhausted and think a nice glass of red wine and an early bedtime are in the offing! =))
