As far as I'm aware, they're pretty up to date with contact forms. I'd recommend sending a new one if you haven't received a reply yet - check your inbox (and your spam filter!) before doing so. If you still don't receive a reply within a few weeks, you can private message me, or any other EN staff member, and we will forward it to them. Make sure to fill out the contact form in english!
In the future, please ask staff related questions in the Staff FAQ. You can use the Questions & Answers thread if you have any other questions about the game/forums, instead of creating your own thread.
