Email from a student this morning (NHBCTPTG):

Title: hey sir
Body Hey i think you have forgotten to give the password for the resit material. I was wondering it email me the password. You email me on <hotmail address>

My reply was measured and politely suggested that the student was a rude, thoughtless idiot for committing this offence against the primary tongue of this country ;-)

Moral: Email is a very convenient communication tool but it's easy to come across as a thoughtless idiot who couldn't be bothered to put any effort into the message! Put some effort in and you're much more likely to get some effort out.

In case you don't understand how to write a decent email or even can't see what the problem is, here are some links to pages discussing "netiquette": our-kids.org, From Kass Johns -- scroll down a bit!, George Dillon and a Google search.
