Hajimemashite. Watashi wa tomomi desu!
Kono kurabu ni hairitai. Ii desu ka?
Hello, I'm tomomi.
I want to join this club. Is it okay?
So, I'm not to sure how to translate "Hajimemashite" and I studied Japanese for 2 1/2 years!! Yeah, that's sad... I'm a idiot!

Because I don't want to forget everything I learned during that time I would like to join and practice a little.
