Can I rerate a public speaker or presenter which I previously rated?

If you have already rated a public speaker or presenter, you may later change your rating, including your comments or review.  Rerating may be useful if you change your mind about the speaker and wish to change the speaker rating and review you previously generated.

To rerate a speaker or presenter, go through the same process for rating the speaker.  See Frequently Asked Questions: How do I rate and review a public speaker or presenter?
