I wish TER provides ability to save review as draft before submission.  Sometimes you get interrupted and you have to get back to it later.

I type my reviews on word processor, save, edit if necessary, then cut and paste into the comment boxes.  Works just fine for me.

That only works if you use only one computer.   Also the other entries cannot be saved this way.   Anyway, I appreciate the suggestion.  It is better than nothing.

Just hit submit anyway and somewhere in the text of the review where you write, say in CAPs that you are not finished.  Has always worked for me...
