To be fair, the first article I submitted to your publication may not have been my best. You were perfectly right to reject it because you felt it wasn't what you were looking for.
Regarding the other recent article, you said there were errors. I re-checked, and found one genuine error picked up by Grammarly and corrected it. The others were incorrectly flagged by Grammarly. Grammarly does sometimes make mistakes, and I'm not the only writer to say this. Recently, an editor made changes suggested by Grammarly which were incorrect, and they did this without telling me. Other writers have previously written about how publication editors should not rely too much on Grammarly and other such tools. In fact, a while back, over-reliance on such a tool caused one editor of Illumination to be fired.
I asked you which specific errors remained that you wanted changing. You did not reply. Instead, you just rejected my article without any further discussion. Was it because they were British spellings?
Since my genuine and good faith efforts to try to work with you to edit my article failed, it's pointless me being a writer for your publication anyway.
