As you will have seen there were ~20,000 WUs up for grabs earlier today and they are now all gone.
We hope everyone got some as they were around for a few hours, this is hopefully (but no guarantees)
the start of similar batches appearing more regularly.
There was an initail minor hitch when they were added to the server that no one was getting them but we've sorted that for the future.
Any questions can be dropped in the message boards, but not about when will there be more WUs.
