Hmm, can't find there the email for invitation via "Single Email Recipient" (from here http://www.geni.com/invite/choose_address_book) :-(
And another one question: after recipient accepting my invitation his Geni account by default on English not Russian. Is any way to change that for me and maybe for rest international users?
This is a problem, cause in most of cases they starting to create profiles not on native language (it is wrong from point of view of Geni's official recommendations) but on English, so I can't see their profiles in my "Profile Matches".

If he/she arrives to Geni pages via the link given in Your invitation (sent and arrived in Russian) then the pages will be (independently of his/her browser settings) in Russian.
If he/she (after reading your e-mail) will just enter into the browser www.geni.com then the Join/Login page will be according to his/her browser preferences - if Russian is highest preference - then in Russian.
Юрий Петрович Чернявский The chosen language of Geni has absolutely no relationship to alphabet used by user inputs.
I can write your name in as Юрий even if all Geni is in English, but I can also write Jurii or Jurij or Iurii or Yuriy or Iourii even if my Geni language is Russian.
I really understood your Geni "Profile Matches" problem - for Cyrillic names it shall at lest compare names between Cyrillic original and minimum 5 different latinization/romanization (Transliteration + Transcription) tables. Currently there is no such functionality included...
I think that similar problem exists for Arabic, Hebrew, Greek, Korean, Japanese, Chinese, Indian etc languages.
