This issue with other languages did not happen in guild, it happened in open chat with other players. It should not have been addressed in guild. You should have gone straight to Tynon to ask about any language requirements they may or may not have (like Evony does). It might also help Tynon if you give them the names of those who are not speaking English in open chat, so that Tynon can do the right thing.
