Ambassadors???

n. 1. A diplomatic official of the highest rank appointed and accredited as representative in residence by one government or sovereign to another, usually for a specific length of time.
2. A diplomatic official heading his or her country's permanent mission to certain international organizations, such as the United Nations.
3. An authorized messenger or representative.
4. An unofficial representative: ambassadors of goodwill.

yeah, i guess thats what they are.. defenition 1 doesn't fit, definition 2 doesn't fit, definition 3 doesn't fit because we have obviously seen they have no real power according to all the posts by jack.. 4 seems to be the only one that fits: unofficial representatives with no real power.
