Good call on not clicking the link, More than likely its a link that will embed some spyware or something. I never click on links that I don't trust. nor do I open emails from addresses I don't know either, I have had viruses and other stuff in the past. My wife opened a spam email once and next thing we know her email account had sent out over 5000 email promoting viagra to people in her address book and other adresses we didnt know. Just be carefull when it comes to stuff like this.
If you're lucky enough to be on private land and can leave your stand up during the off season you can tie an old piece of cloth or something of the sort to your stand. I like to use an old camo bandana that I have. That way the deer get used to the movement and eventually don't bother even looking up when there is slight movement. This may just give you the time to draw your bow or raise your gun without being detected.
