So I've been browsing bits of the forums, and I've seen the notion of 'daily prizes' pop up several times. But I know nothing about them. What exactly are they and is it possible for me to claim one at all?
Daily prize is that little box next to your avatar/account details ->
Click on it and you'll get a Mystery Box. To open the Mystery Box, go to your inventory, locate it, check the box and press "use". It'll give you a random amount of silver, an item, or gold.
