Sue, when you see a link in an email message, it may not be what it appears to be! The link might be printed as email@example.com or http://www.ghi.com
but it does not really either send an email to that address or, if it's a website, it does not really go there - instead it goes to some spammer's website where you might get a virus or spyware installed on your computer or you might be asked to provide information that they could later use for identity theft or other fraudulent activity.
The way to see what the link REALLY is: if you hover your mouse over the link, you can look in the left bottom corner of your window and where the link will go is displayed. Whatever you do, DO NOT CLICK ANY LINKS unless you are positive that you want to go where they are going, not where they only look like they're going!!!
