My First Day    Capitalize the first, last, and all other words in a title, EXCEPT: articles, prepositions, coordinating conjunctions, the word "to" in the infinitive of verbs, and the conjugated forms of the verb "to be."

This is my first day on this site.
Sometimes I need an interpreter or a dictionary to make notes/entries in a notebook, or in order to communicate with people. But I'm learning English, and I hope that in the future I'll know English better than my native Russian. Good luck to me!  Good variant:  "Wish me luck!"
Don't forget: I can help you to learn Russian.
Люблю русский ! :)
