What Joost says:
So, now all tokens have expired for this round. If you have just invited friends, don't worry, their invitations will still be valid. We are moving into next phase in which we will have a nifty invitation feature in the client, so you can shoot off invitations while enjoying full screen TV happiness.
And as for all you who have been waiting for more tokens, your patience will be rewarded :o)
I haved given away 4 tokens to some visitors of my blog, and i never received a single thanks back :(
That sucks a lot :)
