My work

Yesterday, I registered my account there here. And I love your site! I like this website! Because some times later, after(здесь вообще идет будущее время) when I wrote my first note, three or two people persons(users) have(не нужно в данном случае. хэв - перфект,а здесь просто прошедшее) commented it and one very good man have(то-же самое) corrected my mistakes.(Thank you guys). I'm not shure, that if in this note I make made fewer less(лучше) mistakes,(про запятые тоже не забываем, тк не поймут люди) than in the first one.
So now(одно из двух слов, лишнее зачеркнуть =) ), I am sitting in the university on my daily work. I'm system administrator now. Two days before they hired me on this job. I like it, but I don't underestand anything about how to administrate server(work with??) with the Oracle database. It is(между It`s Its большая разница. это есть и этого) so hard for me. How(Like лучше) they said, my salary will be about 4500 rubles or 150$ per month. So, what you say. What about salary in your university. Maby Maybe someone know the Oracle database and helps me with it.
And when I get my first money, I am going to get the a(the - конкретного учителя, выбрал уже. а - какого то учителя, просто нанять его) teacher there here(или вообще ничего), because its it is(выше написал по этому поводу) so cheap!
Good day to you, friends.

Ну смотри, артикли, орфография и времена. Конструкция предложений правильная. И вообще достаточно неплохо, мысли выражаешь, слова используешь хорошие)

А вообще по теме...очень сочувствую..4500 это жесть. В каком университете, если не секрет?

My Work

Yesterday I registered my account on italki. 1. I think my appreciation to the site is growing fast, because after I published my first entry  two people 2. commented it and 3. a very nice man corrected my mistakes. I am greateful to you, guys. I'm not sure whether there are less or more mistakes in this note than in the first one.
4. At the moment I am at work, I work for a university. I'm a system administrator. I accepted the position of a system administrator just two days ago. 5. I like the job but I don't understand anything about the administration of the server with Oracle database. It is so hard for me. They said to me that my salary would be about 4500 rubles or 6. $150 per month. What are the salaries in your universities? One more thing, there might be someone here who knows the Oracle database and helps me with it.
When I get my first money, I am going to get a teacher from italki, because 7. it is so cheap!

Good day to you, friends.

Hello, Lectricas!

Good work on the use of vocabulary and expressing the ideas. Some moments:

1. "to love" has the meaning of affection to a human being, not an object. So use "to like" or "to appreciate" etc.

2. When you just enumerate the events, use Present Simple.

3. A very nice man - "Nice" is a broadly used word for objects and people, "nice" has the hint of kind as well.

4. "I am at work."  is a common used phrase, you don't need to use Russian structure here.

5. Use in your essays as many nouns as possible, avoid using pronouns.

6. The symbols for money are always placed at the front of the numbers. Eg $40AUD, $400USD etc.

7. There is a difference in "its" and "it's=it is". Its is a possesive pronoun. Eg This is a dog's mat. This is its mat. vs It is a nice day! Where "it" is a pronoun and "is" is a verb.

Good luck in your striving for the language!
