YES - from Oxford

Finally got an e-mail from Oxford, saying that I've been offered a place and they sent the letter to me by mail about a month ago. Nice :) Great. Fantastic! Wo-hoo! I have a chance to become a great Computer Science specialist :)
So I'll have to wait for the letter to come and then, I hope, I will know all the details.
I understand why they want to write the decision on paper, but why not inform people by e-mail before the letter comes? It would be great to have a letter on the 1st of May, saying, 'If you do not contact us until the end of April...'
