Looks good. Nice and simple.
You have a little too many different font sizes (forgotten password, some results... Home.Stats.Join, Join LabWaves, The count so far.. are all different sizes). If you could keep to 3-4 different font sizes, it would look a little better in my opinion.
The Join LabWaves green box needs to be center aligned in that blue div, the same with the "Some results" text.
It'll be interesting to see the site with some more content.
