I am afraid I might forget some Russian both Sign language and writting because I havent met anyone and nor used in it here since I alone came in USA last April 1999 year, most often use in English writting and talk with people/interpreters in ASL/ESL/others. But when I met some native language I could remember to understand them but myself to tell them I'm lost* forgot what to say in Russian I will go ahead in ASL mixed with Russian, heh.
I have been in Ukraine all my childhood til my 16 moved in Moscow, Russia for 3+ yrs then returned to home in 1 yr to come in USA at my 21, now I am 28
