Does anybody know of any trans friendly dating sites or personals that are 100% free?

The reason I ask is because sites like Plentyoffish.com and O.K. Cupid act as though the Transgender community does not exist. They only have two options Male or Female in their "gender" selection processes, which to me, seems pretty ridiculous. Not only that, it is so hard to find any sites that aren't paid sites or somehow linked to Adultfriendfinder or some other porn site. Can anybody out there help?
