Hello!

I haven't been posting in this thread for a long time! (I got a warning that this topic has not been posted in for at least 500 days.

)
So I have a few questions, if anyone could help me that would be great!

Someone asked me if I could check an English letter that she wrote which has to be pretty formal! And she doesn't know English that well, and I really don't know about formal letters so I'm asking if anyone here knows.

1. So... the letter is not for one specific person that she would know, so she started it with:
Dear Mr. .... That kinda doesn't seem right to me so I said it would be better something like: Dear Sir or Dear Sirs.... what do you think? can anyone help me with this?
2. She wrote: I am ... (name), student of...
Would it be better if it was: I am .... (name), I am a student of... or at least: I am... (name), a student of...
3. She wrote a sentence like: Can you please check for me, the real date when father C. was there and what was his work.
And I corrected it like:
I was wondering if you could please check for me what was the real date when Father C. was there and what his work was.
but it still doesn't sound all that great... I mean I tried to change the sentence as little as possible but... I don't know... any advise?
4. One more sentence... she wrote: Can you, please, write me a name and year of book, where is this written?
And I corrected it:
Could you please write me the name and the year of the book in which this information is written?
Does that sound ok? Also, is it ok without the commas?

5. And the last thing... the ending... she wrote: Best greeting,
and I wrote: Sincerely,
Would it be better: best regards? or something?
That's all... if anyone could help me that would be great!!!!

(and if not that's ok too

)
Thank you very much!
