How to Correct Writing


I apologize in advance if this is covered in an old post, but I couldn’t find anything.

Can someone direct me towards a tutorial on how to respond to someone’s writing sample with a correction?

I tried to correct someone’s writing on the Writing Exchange. I did this by copying their post into a Word document and then editing it there. I then copied my edits and pasted them into the text box that arises when one clicks “Correct Writing.” Unfortunately, the first time I did this my edits were all in black with no strikethrough. The second time, they were all in red, and the entire response had been stricken out.

Any ideas?
