You don't just learn English by searching the web. You use the web to find resources to help you learn English. By resources, I mean digital textbooks that teach you English from your own language, or things like Duolingo, which is less efficient than a textbook but still pretty good. I'm sure it's possible to even find YouTube videos.
The Internet is an extremely vast place. You can find pretty much anything you want, as long as you know how to look for it. If you're telling me that the Internet hasn't helped you to learn English, you probably haven't tried hard enough. This is just me reading between the lines though.
I'm not entirely sure what topic it is you're saying to be struggling with. Is it "l can write to manoeuvre my sentence by own choice of words and avoid some words or contexts creatively."
Because if it is, as I've said before, you are never going to achieve this goal unless you learn the English language properly. Wanting to do all of this is like wanting to build a house without laying the foundation first. It'll fall apart quickly.
Honestly, you're very unlikely to be able to participate in any English-speaking community effectively without a good grasp of the English language. You just won't be able to communicate, and if you can't communicate, you can't really learn.
I have a couple of questions for you:
- What is your native language?
- In your native language, are your writing skills good?
- What is your long-term writing goal? Do you want to publish an English novel and become an author? Obviously, there is a reason you're looking for learning communities. You want to achieve something in the future. Basically, tell me what that is.
- Are you working on a novel or some kind of story right now?
Unless you can answer these, it'll be very hard for me to give you any sort of useful advise.
