<a href="http://www.fordeurope.net" target="_blank">FordEurope.net</a> already has a forum. Although its an established site, there aren't very many posts there. I know that there are tons of Ford fans in Europe... when it comes to modifying cars over there only VWs are more popular.
Language barrier can be a problem but English is widely spoken in Europe. I can't speak for everyone though but in Portugal you are required to study two of the following three languages throughout secondary school: English, French or German. Almost everyone in Portugal that is my age (24) can speak, write and read English to the point where they can communicate well.
I can read and write in French and Spanish but I'm horrible at German. When communicating in German, I usually use a translation tool like the one available at <a href="http://translate.lycos.com" target="_blank">Lycos</a>. Just copy and paste, select the language to translate to and that's it. Many times, the output is not gramatically correct but you're still able to communicate.
