Hi... is there a way to make a part of the Nickname hidden in the Chatwindow?
It's a little bit complicated. Look:

My nickname shoud be like this: "My Nickname (Bla, bla, bla)"

(Bla, Bla, Bla) shoud be visibly for everyone. But when i am chatting, there shoud only be written:

"My Nickname says:"

Do you know what i mean?

thank you
