Message of Greeting.  [Capitalize all the "important" words in a title.]

Hello everyone! In this notebook I want to greet the people who come to my profile, and introduce myself to you, and also to make sure that I am able to do that without any gross mistakes. :)
All right, my name is Ivan, and I'm from Moscow. I'm here mainly due to the fact that at the present time I am learning the English language so far, but in the foreseeable future the list of the languages I am studying will be reinforced/supplemented. [1] The Language studying is one of not many things I'm interested in, and which give me pleasure from the process. I'm even a little bit sorry for those people who have to step over themselves to study foreign languages against their own will, maybe for a job or for something else, whatever, I mean, without their personal desire.  [Magnificent sentence!]
My study of English has already lasted for three years, and I really enjoy it, and I'm looking for someone who might become my language partner, and with whom I could share the studying with. Sometimes I'm being faced with really difficult things in English that I can't deal with by myself. I would very much like to find someone to whom I could ask questions about these things, because I want to become absolutely fluent in English one day, but I'm unlikely to succeed in it without help.
There's a funny thing about my studying! I can't remember when I last watched a movie not in the English language last. :) I usually turn on the Russian subtitle track and watch it in English, so that my studying is being more productive.
Thanks a lot for your attention on this!

[1]  "replenish" would mean that your list of language would grow shorter, and then you would bring it back to its former length.  "reinforce" and (especially) "supplement" mean that something else (other languages) will be <em>added to</em> your knowledge of English.

Your post was extremely well written.
