You might notice that most Americans, including here on the forum, are pretty understanding of people who speak English as a foreigner. Don't be worried about that.
(If you have questions or want to talk about e-cigarettes, I don't speak any Lithuanian, but maybe you know Russian better than English?...так что, пиши мне если тебе удобнее выражать мысли/вопросы по-русски, чем по-английски... Всегда рада помогать!)
