I don't know who you are. or I don't know who are you.
single (you)
tense is unknown, but let's suppose it is present tense.
Francky's translation was good, but he used a past tense.
We'd better use present tense, if there is no time indications.

Thanks for the help, pluiepoco, you've got half of the points.

Well, I don't like points at all. I wanna find ways to spend them. Anyway, thanks!
