what does it mean when people said yours before the name when ending a letter?

It doesn't indicate that the person really is "yours".  "Yours truly" is a conventional ending for a business letter, friendly but unemotional.  An alternate ending is "Sincerely."

The signature at the end of a letter is called the "script".  The "PS" stands for "Post Script" which means "after the signature" ("Oh, before I signed this, I forgot to mention...").

Here in the US, my experience as a child was to call adults Mr or Mrs (last name) as a sign of respect.  If the woman wasn't married, then it would be Ms (last name).  (Ms in that case means Miss, but I have also seen it used to abbreviated Mizz (sp?) - which is used if you don't know if the woman is married.  An example of that would be if you are writing a business letter and the woman to whom you are writing doesn't have a professional title and you don't know if she is married.  In that case, say "Dear Ms (last name).")  The use of Sir and Ma'am would be for older adults that you don't know.  (In other words, no last name is used because you don't know it.)  It has also been in my experience that when you are the same age as the person, you can address them by their first name if you are in that close of a relationship.  Some people with titles, regardless of age, should still have their titles used when addressing them.  One example is religious authorities - Pastor, Father, Rabbi.  When in doubt, if you know the person's name, call them Mr/Mrs/Ms (last name).  If you don't know their name, call them Sir or Ma'am.  It's better to err on the side of being too formal instead of disrespecting them.  Also, if you're not sure, ask them "How would you like me to address you?"  That will help you know if you should use a title, use a first name, etc.  I hope that's helpful.

I once got mails from a guy who always signed with BR and his name. It stood for Best Regards.\nTherefore, I would also suspect it is meant to stand for Regards..

used the word "eh" at the end of a sentence when they ask a question or make a statement.

It's like " I already told you" or "remember this". It's usually used when you ask a favor to someone and that someone denies it, it is like saying "you didn't help, well, I won't when you need it"

Usually you just click on thier name...but I don't know what does it say?

I think they're just being polite and want to know what your name is. I've got a naughty name, my family use my first middle and last names altogether if they think I'm being naughty! I would have thought they'd have stopped doing it now though, I'm 31 for goodness sake!!!

When signing, you always sign your own name last if you are the one signing all of the names. For example, if your name was Mary: \nSincerely,\n                       Tom, Emma, Jake, and Mary\nIf everyone is signing their own names than the order does not matter.

i would go by whatever u and the one u'r separated from agree upon. however, most people begin before they are signed. it's often the cause of the separation

Your signature doesn't really matter. Just finish with:\n\nBest regards,\nYour name

It is a less polite form of Miss.  Usually it is used if someone is being a brat...it's meant to be condescending.  Like "Listen Little Missy! I've had enough of this behavior!"

I think it's just the using of letters. Just like unknowns are usually called x, y, stuff like that.

Exactly, it means as follows:\n\n"Your favorite person in history."\n\nG'luk!

Hiya :-) ! I think it is because the "bye-bye" is more emotionally meant... because, usually, you would say "goodbye"... you are really leaving someone, whereas with "Hello", you would still spend time with the person? I also think the second "bye" really emphasises that. You could just say "Bye" as well, which might sound colder or indifferent. To some people, "Bye-Bye" is just what they got used to. Hmmm :o) ... don't know. Just my thoughts. \n\nCould not read the links yet but will definitely help you... probably :-) . Have a nice weekend :-) !

No, that would show possessive use.  The s after the name is just fine, and actually grammatically correct.

There are a few reasons why they might do this:\n\n1) Because they do not like their full name.\n2) Because they want to appear more professional.\n3) Because they do not want others to have difficult in pronouncing their name (I would certainly do that).\n4) Because they wish to abbreviate or shorten their name.
