I've built a dual language site for a client - English and German which we intend to host at an .eu domain. Each page has a click-through to the other language. All relatively straightforward so far... but what will be the best way to get into each site? Should I have a front page with the UK and German flag and then get visitors to click through to the relevant site? Or what? Or should we host the English site at a .co.uk?
