I am also unfamiliar with the gender of name Tatjana, but I'll take your word for it. My greatest apologies for any insult to Ms. van Vark.</p> I apologise deeply if that is the case – I couldn’t find a single pronoun on the site to give me a clue either way, and the photograph didn’t help me too much either.
