If you're going to email me a Very Important Document that I Must Read Before Training why wait till the day before my training to do it? Not really the day before either, since it arrived in my inbox about 5.30pm - didn't you know all teachers leave at 3.00pm?
Also, if you're going to add an attachment and refer to this attachement in the email, it helps if you actually attach it, it'll save you sending the same email three times in an attempt to get it right.
Finally, why save this Very Important Document in a file format that not many teachers have access too, don't you know how epensive Office 2007 is? Fortunately I was able to download the compatibility software, not everyone will be able to do that.
