More trouble with the college email. The mail is delayed, and the delay is so severe at times that snailmail seems a better option. This morning two of my colleagues received an email from me concerning something we fixed yesterday. It was three days delayed (and no longer valid). If I had walked down to town and posted a letter it would have arrived earlier. Students who come for supervision and mail their work the day before arrive three hours before their emails. Colleagues at other colleges and universities call me when I don't reply to emails which clearly are urgent. I would like to blame spam and spam filters, but apparently that isn't all the truth. The gist of this is: If you don't get a reply to an email to me, it is probably because it hasn't reached me. If it is really urgent - find some other medium.
