Well I’m not a native English speaker but depending on your language level, I really might be able to help. I just signed up to become a tutor so am wondering if anyone is interested in me correcting his/her writings 
I’m not sure how well I can do it but anyways I would love to give it a try…
And by the way is there anyway that everyone can correct writings or should I only be selected by a student?
Please let me know what you think.
Thank you
Students have to select you as a tutor.
To be honest, I submit writings only to persons that I know. That means I prefer tutors to whom I’ve spoken before or people who are very active on the forum.
And I prefer corrections by native speakers. My English is at a level where it isn’t helpful if a non-native corrects it. I’m not flawless, but beside the grammar mistakes I expect that my phrases are judged if they sound naturely etc. And that can be done by natives only.
Probably others have other opinions.
