[Plugin: WordPress-Amazon-Associate] inputting Amazon Associate ID

Hi,

In the Associate setting, am I supposed to input my Amazon Tag id, ie: [name]-20 or am I supposed to input the whole thing, wp-amazon-[name]-20?

This is more of an Amazon question, but I assume we need to register a diff Associate ID with different geo-locations? So if I want a UK ID as well, I have to go to http://www.amazon.co.uk to register and get approval?

Thanks.
