Road to War – One time collection?

Where to get heads for the Road to War game. It seem you can only collect a head one time but I can’t seem to find new ones. For those that aren’t sure what I am talking about, there is a new game coming out next month on the 16yh. In an effort to spread the word about the game the creators of the game Warhammer Online have started a little bit of viral marketing where players pick one of two factions to play for. Either Chaos/Destruction or Order. Then you seek out on the internet for where you enemy has posted their heads to be collected. Once found a clicked on, gold is awarded and can then be used to further the goals of your faction. Any ideas on how to get the daily max everyday?
