I played on Leanon for eight months and I don't know German. Trust me philu (Neela), you'll be fine. Everything will be fine.
Anyhow, a lot of germans and french speak English, it's just the other way around thats going to be tricky ^^
On top of it, I don't know about numbers, but I assume the english and french community are by far bigger then the german one.
Nevertheless, we can always rely on sign-language.... dance once for trade and twice for a fight....;-)
