As this thread is proving, English grammar is very difficult to learn, even to some native speakers.
An apostrophe is the most commonly misused part of English grammar
ie:
"Do not" becomes "don't", the apostrophe indicates the missing 'o'.
I'm not up to giving full English lessons because it may contradict what some non English people have been taught, however my experience of so called American English is like a lot of things American, they make it up as they go along, with rules to suit themselves.
The apostrophe also indicates possession. I bring you to a credible and authoritative source, by far more authoritative than you:

As it says:
2. Possessives
An apostrophe is used to indicate ownership/possession with nouns. To show ownership by a single individual, insert the apostrophe between the noun and the 's'. To show ownership by more than one individual, use the apostrophe at the end of the word.
You've made far more errors in your original post than anyone else's single reply. You used commas in incorrect places where you attempted to use them as conjunctions. You have a 104 word sentence which doesn't flow. Your claim about the use of 're' instead of 'er' isn't always accurate. "Thermometer" uses 're' because we use "meter" to reflect an object which measures, e.g. a water meter.
My biggest problem with what you're saying is that you are claiming to be an authority of the English language, yet you provide no evidence of your qualifications. It's alright to make suggestions on improvements, but claiming you have qualifications, and then making erroneous posts doesn't reflect too well.

If I were a qualified typist then I would be expected to remember things like a full stop, at the end of every sentence, as I am not, then I do tend to forget them. Using handwriting I would expect to get it right each time.
The use of a period is very much part of the English language and is a grammatical issue, i.e. punctuation.
