While I could imagine a sale of this name to a David So^^^^^^^(i forgot the dot so rules though)
I did type in two
exceeding common female first names in a dot so search and they are available to regester.
But the few male ones I typed in are taken
So (lol) it looks like the male dominated 'domainers' bought out
their own male dot so domains, but there isn't the female buyout. Which supports the no value to regfee dot so unless you get a sale. Goodluck
