To make everybody's lives easier, both you as writers, and us as editors, we've implemented a new spelling and grammar checker. Previously we had a spell check system that was very basic. We've updated the system and have now implemented a much more complex system. The new system not only has a much better spell checker, it also has an advanced grammar checker and a natural language checker.
This will help improve the overall readability of your content and is right in line with our goal to constantly improve the quality of the content on the site.
