thanks! i know rekabu.ru seems to be a good one too, not sure about szmer.info, it says they speak russian and there is a community for russian articles but it seems more for polish speakers.

oh and ух ты! i think is like a whoa or an "oh wow!’

in my moms language: «ого!»
«вау!»
«супер!» (impressed by something ig) “super!”
