Add "EXPERT-A" or "EXPERT-B" to your character's buddy list. A and B represent the A or B control settings. If you use C or D, you're out of luck for the moment. Now go online and join a dedicated server (has an arrow or star next to it.) Leave and go back to your setup screen. Go to the controls screen, and you should see a new setting which has replaced A or B. The main reason to use this is that it lets you throw the flag!
NOTE: Adding EXPERT-A or EXPERT-B to your buddy list also lets you use CHAT-TEST, so you don't need to have them both on your list at once.
While in the menu for your charactar click ''buddy list'' press add then enter CHAT-TEST. During gameplay (on a server) press square and then there will be a list of options press whatever direction you want(right corrisponds with square, left corrisponds with circle, up corrisponds with triangle and down corrisponds with X) When you press square during gameplay you can't do anything but pick options so make sure your not in a duel with another person
