We offer the spell check feature as part of our premium membership. To turn on spell check, click the wrench icon in your weekly view.
Here, you will see the option to turn spell check "on" or "off".
While you are editing your plans, misspelled words will appear with a dotted red underline.
If you don't correct the word, the misspelled word will appear in red in the daily, monthly, and weekly views. If the word is an abbreviation or other word that you do not wish to edit, you can edit or quick edit the lesson box again, click "save", and the red will be removed.
