Ditto to what Eric said, I really don't understand what they mean by "front shoulder press"....in my book thats a military press because the bar is in front of you and your are pushing it up above you. Unless you are talking about some sort of machine labeled front shoulder press I just don't understand the difference.

That being said I personally do standing military presses and don't do any work behind the neck, just like Wolf said I think they can be dangerous and they put your shoulders into an unnatural position. In my opinion you are just asking for shoulder problems such as impingements and strains if you choose to do them. Your shoulders are easy enough to mess up in the first place, not worth the risk.
