XF 1.1 Why don't I earn any trophies?

For the first trophy to be earned you have to create a message. What is the meaning of "message"? Is it to create a status message or to create a forum post? I have created both on my site but haven't gotten any trophy.

Do you have to enable trophies somewhere in the adminc cp? Or does it take some time for trophies to appear?
I have newly installed Xenforo, so all the trophies that comes with the install is those I have now. What is periodic cron task? How long do you have to wait for that to run? Once a day?

Thanks for your fast reply =)
Aha.. thanks =) ! But one more question.. it didnt seem I got a trophie for my status message. Should I get that or is it only for creating a forum post?
