Creating an additional English language user registration form

I'm running a drupal site in a foreign language as default. I do need an English language registration form as well, which means that the I need the user profile fields in English. Having been reading various forums all day long I found that i18n module would do it for me. I installed it and turned on 'Profile translation' function. After all, I got stuck. There is no user friendly interface: I cannot see 'Translate' link under /admin/user/profile, i dunno if its okay. Then I created an English .po file from the original profile .po, imported it and the message was 'The translation was successfully imported. There are 0 newly created translated strings, 0 strings were updated and 10 strings were removed.' After all it still doesn't show the English titles and fields, only the original ones, no joy, even if it's switched to the English version with the English prefix (under /en/user/register).
What have I done wrong, what have I not done, how can we solve my problem?
