Forum Grammar - Don't Look Like a Clown

I read (and respond) to a lot of forums.  And time and again I see people posting on forums (using their real names, nonetheless) who just haven't got a clue when it comes to grammar.  I try very hard to be grammatically correct because it bugs the you know what out of me when people either don't know how to be, or don't care to be.  So, in order to help the community out, I wanted to provide some tips.

#1) There, Their, and They're are three different words (well one is a contraction).  Either way, they each have a different meaning.  A different use.  You cannot just pick one at random when constructing a sentence or you sound like a tool.  So let's review (in layman's terms): THERE is a location.  The book is over there.  THEIR is possessive.  That means ownership.  That's not your car it is their car.  THEY'RE is a contraction, meaning THEY ARE.  They're coming around noon.  Ok, good.

#2) "u" is "you".  U are not cute when u show that u are too lazy to also type the "yo" in front of the "u".  "U" may be suitable for character-restricted text messaging, but it isn't suitable when trying to convey your ideas & opinions without looking like a tool.

#3) Proper nouns like Hellertown should be capitalized.  I know, I know.  It's a pain in the a$$ to have to capitalize letters.  But fortunately, when they designed the modern keyboard, they gave us TWO SHIFT keys to capitalize with.  So just pick one and capitalize proper nouns.  

#4) Punctuation.  There are a lot of options.  Periods, exclamation marks, commas, colons, semi colons, etc.  Try to incorporate some of these more rare symbols into your sentences.  They make you look smarter than if you just type a bunch of words.  By the way, than vs. then is also a good one but you can research that on your own if need be.

#5) This one is debatable, so I will just throw it out there.  Typically, it's more acceptable (notice the apostrophe in it's - that's a contraction) to spell out numbers that are less than ten and numerically represent numbers that are 11 or higher.

#6) Irregardless of what you think, irregardless is not a word.  You mean regardless.

#7) If you could care less about my grammar suggestions, then you care a little bit, but could care less.  If you really couldn't care less, then I feel bad for you.  Note the difference and stop saying you could all care less, because that's silly.

And if you ever get confused - Google is your friend.
