PlentyofFish Larger Than Other Free Dating Services Combined

OPW -- Aug 25 -- I took a look over PlentyofFish this morning to see Markus is listing PlentyofFish as the, "3rd Largest Dating site in the world, larger than all other free dating services combined."  Looking at the Hitwise rankings...he's certainly larger than all the other free dating sites combined at this stage, but for the world?  What free dating sites do you know of worldwide?  Your comments please.  I just came across Amoureux which is big in France and makes it's money off advertising and mobile usage fees.  - Mark Brooks
