"Most of us (if not all) are writing in English, be it writing some chapters of novel or comics, comics, posting in the forum, etc. and I believe most of us are not native speakers... yet somehow, quite surprisingly, it seems like there's still little discussion on language usage itself and (feared-by-many) grammar rules. Feel free to discuss anything grammar-related or any other interesting English language-related things here :3. It does not matter whether you don't really care about writing with perfect grammar (neither do I) or you are spending most of your time worrying and praying you don't make any grammar mistakes when publishing your creative work online. Maybe we can improve our work quality."
...That's all I could spot. ^^;
Although it made me think of something kind of important when it comes to language usage: there's a difference between being grammatically correct and being "natural".
For example, I corrected the phrase "spending most of the time" to "spending most of your time". Both are technically grammatically correct (even in context), although the former would be immediately recognized by a native English speaker as "unnatural". That's just not the way people say that phrase.
Unfortunately, since English is such a weird language it's absolutely riddled with stuff like that...for example, the adjective order thing. It's really cool to think about, and I think other languages do it too:
"the big old blue dog"
^That is the only "natural" order for the adjectives to take in that phrase. A mature native English speaker would not say "the big blue old dog" or "the old blue big dog" or "the blue big old dog", etc. Why? I...do not know (I think it's possible that there isn't a reason).
We aren't even taught this explicitly, it's just something we all latch onto as we grow up in this language community. ^^
