anyone can suggest changes but ordinary users (like me) can can only issue a pull request (to merge the changes) which should be reviewed and approved by admins

Can I issue a pull request by myself, or should I ask here every time I think an English message should be changed?

yes, you can. u just need an account on github and a basic understanding of git. here're the files with the strings: https://github.com/inaturalist/inaturalist/tree/master/config/locales

Thanks :)
