Dude, read again what I've said. It's not that I intended to offend any non-native English person, neither am I.
The intention behind my post is that I, personally, feel that Codemasters should also focus, when choosing Beta-testers, on the ability of speaking English. The more precise you can be, the better it is for Codemasters to understand your feedback and problems with the given game.
I agree with you saying: "F1 is worldwide. Not just for English speaking know-it-all. Otherwise Codemasters F1 would be in pure English. This forum is for everyone." This is the intention behind a forum, to connect people worldwide.
The thing is, as I've stated earlier, if you're not in the position to speak English properly, you shouldn't be a beta-tester. As it really gives kind of a barrier in communication and making your feedback less quality, which would negatively impact the development of the game.
It's like a job-interview for a company with huge international connections where you need to be in the position to communicate with your partners and if you're not able to talk in a proper way, it hinders the success of your company.
By testing the official F1 game you have a huge responsibility, because Formula 1 is worldwide, as you said yourself.
I hope you understand this clarification of my opinion!
