Grammar explanation
We use both the present perfect simple (have or has + past participle) and the present perfect continuous (have or has + been + -ing form) to talk about past actions or states which are still connected to the present.
Focusing on result or activity
The present perfect simple usually focuses on the result of the activity in some way, and the present perfect continuous usually focuses on the activity itself in some way.
| Present perfect simple | Present perfect continuous |
| Focuses on the result | Focuses on the activity |
| You've cleaned the bathroom! It looks lovely! | I've been gardening. It's so nice out there. |
| Says 'how many' | Says 'how long' |
| She's read ten books this summer. | She's been reading that book all day. |
| Describes a completed action | Describes an activity which may continue |
| I've written you an email. | I've been writing emails. |
| When we can see evidence of recent activity | |
| The grass looks wet. Has it been raining? I know, I'm really red. I've been running! |
Ongoing states and actions
We often use for, since and how long with the present perfect simple to talk about ongoing states.
How long have you known each other?
We've known each other since we were at school.
We often use for, since and how long with the present perfect continuous to talk about ongoing single or repeated actions.
How long have they been playing tennis?
They've been playing tennis for an hour.
They've been playing tennis every Sunday for years.
Sometimes the present perfect continuous can emphasise that a situation is temporary.
I usually go to the gym on the High Street, but it's closed for repairs at the moment so I've been going to the one in the shopping centre.

Hi Melvin,
The Cambridge Dictionary (see the ‘Negatives’ section) agrees that already in negative sentences refers to something that should have happened, while yet is for something that simply has not happened. You may also find interesting discussions of this question elsewhere online (e.g. this Stack Exchange discussion).
About the different explanations that you’ve heard from different teachers, I would say two things:
If you’ve already registered, thanks a lot! If you haven’t already registered, …
But with an example sentence abstracted from context, two people could look at it and imagine totally different contexts of use, leading them to give to different explanations.
It is possible that there are differences between British and American English usage here. But in general, we should also consider other explanations. For example, perhaps those teachers you mentioned had particular examples or a particular lesson or a particular context in mind. Or perhaps their intention was to give an easier-to-understand or more practical explanation. It’s hard for us to comment on other teachers’ comments – it might be better to follow up with them.
I hope this helps in some way, but I'm afraid it may not be possible for us to ‘clear up your confusion’ as you put it – as you can see, even language teachers have differences of opinion. But perhaps this is only natural with something as complex and diverse as language usage.

Hi Melvin,
Although compared to yet gives a stronger sense that the speaker expects the action has in fact been done. For example:
So, the already version may be used if a speaker expects that you have in fact contacted him, but just wants to check or confirm it. The yet question may be used when the speaker is pointing out something he/she thinks you might have forgotten to do or haven't done in time.
About your second question, yes - in modern usage, already is used with the past simple (as in your sentence 3), even though traditionally it is taught that it should be used with perfect verb forms. But the verb form in sentence 2 isn't right - (doesn't) become in the present simple doesn't work. It should be in the present perfect (or past simple).
I hope that helps.

Hi Melvin,
Yes, as far as I know. I would also add that:
I hope that helps!

Hi Ahmed Imam,
No, it's incorrect because met is a momentary action, but since shows the action had a duration until the present. So, here are two corrections we can make:
I hope that helps.

Hello Team.
In Cambridge Advanced Grammar in Use; 2nd edition Page 6 unit 3, I found the following sentence "Have you met any of your neighbours since you've lived here?" The book used "have met". What do you say? or what is the difference between my question and this sentence?
Thank you.
Hi Ahmed Imam,
OK, yes - let me make a correction. It IS a correct sentence if the intended meaning is "I have met John in that time period" (i.e. from September to now).
Reading the original sentence, that meaning did not occur to me at first, perhaps because without knowing the context in which this is said, it is unclear why September is significant for the speaker. That's why I interpreted the sentence as about the length of time that the person has known John. (In this meaning, the significance of September is clear - it's the time that John and the speaker first met.)
Perhaps this is a good example of the importance of the context for interpreting meaning :)
