To be honest, the forums are kind of dead. I only check them like once a week.
But, to answer your question, the only personal information I can see is your email address. No one else but me can see that, and it remains confidential. If you don't want me to know it, you can make your username something that isn't related to "Caliphate of muslims" that way, I can still see your email, but I don't have any idea of who you are.
Also, I really could care less about emails. You don't have to put one in if it's optional.
