Correct question : "Who administers this site now? If I have any queries, who should I get in touch with."

Hi Cherry, As per usual, you can contact the admins via the support page (there's also an email address): http://support.italki.com/home The guard has changed, but you're still talking to human beings. :)

Who is administering the site now? In case of inquiries, to whom do I contact?.

I wish I knew the answer. Who does run this site?
