I voted for pnnv.com as one of the alternatives and I'm also using it right now, I don't know about the others, so far PNVV is making an impact by running an avatar campaign and I read that they will soon launch a signature campaign the design is very much similar to the old Preev and its ads free, surprisingly.
I wonder where they are going to get the revenues the admin spends with money out of their pocket to promote this converter.
and it's also the choice of those who voted.
