I'm not sure if this may just be me, but I can't use the alt-key in combination with another key in order to get a special sign out. For my dutch keyboard that includes the @ sign, which heh, I kinda needed to enter for the invitation mail.. Was kind of dull that I had to change my keyboard lay-out to another so I could enter that @ without needing the alt.

Is it just me having this issue, or is it really not possible to use it in-game?
