Word to the wise: webmail woes

This is an issue that has cropped up a couple of times at the university where I work.

If you send yourself a document that you are working on, to continue working on it on another PC, remember to save the attached document onto that machine before you start to make changes to it. It is easy to forget this, open the document and start making changes. If you then hit the save icon it will not always save and when you then close whatever program you are editing the document in, your changes will be lost. This is particularly the case for documents accessed via webmail. If you remember to 'Save as' rather than just 'Save' you will be OK, because it will prompt you for a name and location where you wish to save it. Nevertheless, it is better to get into the good habit of copying the document you attached to the email onto the PC before you expend effort making alterations.
