Gameplay
After you "choose" your character and weapon you'll have to click the "New Topic" button.You can't click it most of the time, so just hover your mouse over it until it stops moving for half a second.
Alternatively just use Tab to block the button.
After that you'll have two choices...I would suggest trying both of them out.
