6. Test run your work with plagiarism checker:
That feeling you have when you run your work through a plagiarism checker and discovered that your work is 0% plagiarised and 100% unique. This is what your indicters use, it will be cool you use it on yourself to know the quality of your post before publishing.
I dont think this is necessary. If you composed a sentence or make a topic, its really unlikely that your composition will be flagged as plagiarism on a checker. You know it yourself if you did copy someone idea word by word but if you knew to yourself that you wrote something out of others content then theres nothing really to worry about.
Only someone with intent to plagiarize will use a checker. But the chance of you writing with the same word by word in a sentence is totally impossible.
