Yes I agree with dman, I keep pronouncing it with the s.
But apart from that I dont like .ws very much, as I understand it, it is not possible to transfer .ws domains to other registrar's. I would never buy a .ws, cause you are stuck with the registrar, you have registered it with, so if you sell to others, then they also have to be in that registrar.
So I would just say reg. value, sorry friend.
Best regards.
