Here is the best way to create a link which everyone will view the same and which will last:
Order the reviews chronologically (not antichronologically). If your default direction is up, press the button twice. Select My reviews only in the drop-down box. Change the I.D. number in the U.R.L. from yours if applicable. Change Start=1 in the U.R.L. if applicable. Change Rows=100 in the U.R.L. to Rows=1 if there are later reviews and/or you want to be tidy.
This link will only break if an older review by the same person is removed or approved, i.e. not very often.
