I wasn't a native english speaker, but I been speaking it for 20 years now and I still make many of these mistakes on the list. Good stuff.
Glad I could help.
Another error which is quite common is the difference between its and its.
It's on the list number 26.
Because some of the members here, their native language is not english, and I do believe some of the user out there use google translate in their post.
Again, if they are using Google Translate, they won't make spelling mistakes, they would make non-logical sentences that make no sense. Besides, Google Translate is getting stronger and smarter nowadays, I give them that.
