Could I please get some best practice tips on how to automate Distribution Group Membership in Adaxes please?  
For example:  
I have a group "UK Staff"
I have Tom and Dick who have the AD "Country" field set to UK
I would like to run a task each night that will add them to the UK Staff list  
But..  
Tom moves to the USA
I have a group "USA Staff"
I would like to run a task each night that will add Tom to the USA Staff list  
But I also need to remove Tom from the UK Staff list automatically which is where I'm not clear of the right/neat way to do it?  
Thanks :)
