Could someone please explain the difference between these two?

Russianin?

Hi everybody!

I just came across the word "russianin" in a newspaper text. Since my dictionary doesn't know this word either, I thought I should ask you. :) To me, it seems like a mix of the words "russkij" and "rossiianin". Does "russianin" exists as well, if so, which connotations has it?
Thank you so much in advance! Spasibo vam bolshoe!

Hi, I was wondering if anyone's every participated in the Russian Olympiada? It's at Temple University(well, for me at least. I'm not sure if it's held in other parts of the country/world/etc). Basically, it is a conference you go to and you get to practice Russian. You speak it with some Russian professors and you're scored on fluency, pronuncability (word? lol), etc. If you've participated in it or something similar, how can I prepare? They gave us a pamphlet with information, but it's entirely in Russian so I'm a little confused haha.
