Dear Village Idiot,

Thanks for your reply. I know there have been several issues on this, however I was actually hoping to find someone directly in Zug. I will checkout your link, and thanks again.

I ended up going to a firm in Zurich. It's listed in the Tax thread somewhere.

Does anyone have Denise Collin new details as my email was returned 'undeliverable'? thanks
