Is there a way to save a review before it is completed and then come back and finish it later? Or do I have to complete the review all in one sitting?
Not on line.
Many will use the format of the reviews and write it using a program like Word.
They save the draft, and have the word processing functions like spelling and grammar checks.
If they should have to leave the review for a bit they save it, and then finish latter.
When ready to post to the Board, they copy and paste the different sections of the review into the proper places in the review.
