It's automatic.
You still have admin powers, all thats changed is the colour of your username which I can change back to orange if you wish
I've also changed your rank back to "Ugliest kit car champion"
I can only test the country option to a certain extent due to not being able to read all the languages it offers.
If you can cope with English then its best to leave the country as the UK.
If any members from other countries do donate and change the country in the option box, please let me know if it works or if you get any errors so I can track down any bugs etc
