If a paper is presented well, is well organized, and is clear, it is likely to be accepted even if the English is so-so.Co-authoring with experienced researchers can be a great experience (Combination of specific skills of authors!).MUST reference some papers from the journal in your manuscript (if you do not –you are giving the editor a reason to say your paper “does not fit their overall scope”).If more ideas or themes come to mind, state it as future research in your conclusion and split it off for future publications.
