Suggestion: Use a tool called Grammarly.

Just to give a suggestion to the writers, look into a free tool called "Grammarly". It's a very good spelling and grammar checker that's really fast and explains why you should write something in a specific way. It's a plugin that integrates well into Google Chrome and scans anywhere there's a text box. Works much better for me than the standard installed spell checker for Windows, but I haven't done a comparison between the two.

That is all, good luck out there!
