How to correct written texts

I don’t think I have understood how to correct written texts. I tried to but …

Can you explain it to me, I saw the video but I don’t seem to be able to do it.

Thanks!

@Elfgal - do you mean correcting other members’ texts? If so, click “submit a response”. Then, in Original version highlight a word/phrase you want to correct and click “new correction” at the top. This word/phrase will appear underneath where you can type corrected text, define a type of error and leave some notes. Then click “save” and move to the next part of the text.
