Are these sentences considered correct?
1 I want make interesting friends around the world.
2 I can find more friends from another country.
3 I can meet interesting friends from korea, England and many more (countries) through the website.
Sentences (2) and (3) are OK, except for the fact that you didn't capitalize the "K" in "Korea." But (1) is incorrect.
You can't say, "I want make interesting friends around the world." You can't ever say "I want make." You can say, "I want to make . . ."
