Here is modified version to work with google.bg. Basicly you should only change the domain names, but in bulgarian version the logo image was set as background for a div tag and called logo_plain.jpg, so I add one more rewrite rule. It have a bug - the "Bulgaria" caption is too far from the logo, so if somebody can fix the position or just hide it, please post the fixed code
