My English grammar is awful even though my English vocabulary is good (this is why I'm doing only technical edits in the English Wikipedia) in order to improve my grammar I have started to chat with people on the internet (mostly on Reddit but sometimes on Twitch and Youtube) when I'm thinking that I did a grammar mistake I'm searching on google to check if I actually made a mistake and if I actually made a mistake I'm writing the mistake here in order to remember the grammar rule that I have learned from the mistake.

Mistakes
In this edit on the Hebrew wikipedia I wrote: "I know that your administor (administrator) but I just wanted to be the one that sent u the welcome message" (i know that the but was unnecessary and instead of but I should have used the comma sign). then I have checked if I did a grammar mistake. The question that I asked myself was: the one that or the one who? The answer is: "Rule Who refers to people. That may refer to people, animals, groups, or things, but who is preferred when referring to people. Example: Anya is the one who rescued the bird. NOTE: While Anya is the one that rescued the bird is also correct, who is preferred"
