Farewell Italki! It seems that the recent italki's upgrade (from 2014-04-03) is incompatible with Firefox prior to version 15. Currently, my roster looks empty; I cannot see any social and language updates, cannot read private messages as well as read and submit corrections and comments -- basically I can do almost nothing. Very unfortunately, upgrading Firefox is not an option for me, as the recent versions require libraries which conflict with ones used by the operating system itself. As it is very unlikely that backward compatibility of this website will be fulfilled one day, it seems there is nothing to do but wait for a moment when I will be ready to install a new operating system. In this respect, I am grateful to the Italki's community for an affecting experience. I would also like to thank my "friends" for interesting conversations over Skype, private messages, and even offline. I hope we will continue our communication regardless of any circumstances.
