Sorry. We did not change the FAQ
We added Check Spelling as a modification. It was not built into the system

To use the checker: write your message and simply press "Check spelling" instead of "Continue"

The checker is not too smart

...
Check the suggestions for changes, press apply...

After you are done you must copy the results from the checker and paste them to your post.

Or edit as suggested by the checker

Sorry. That is the best we could find without having to pay a fee for each user.

Is there a better way? Please let us know!

Best wishes
