What does this mean? I think it has something to do with introducing oneself but I´m not sure.

kendinizi tanıtırmısınız....sizi tanımıyorum sanırım

Thank you!

 can you introduce yourself,I don´t think I know you.

Thats what I thought..just wanted to be sure.  Thank you

 Can I use the same phrase in turkish if I want to write it ?  or.. is it only for speaking? Thanks.

 It shouldn´t matter.   FYI This phrase uses the more formal form of "you".   (...siniz   and sizi)
