How to allow users to edit their own comments?

To allow users to edit own comments you need to log-in into the wp-admin->RateMash->Settings

In the Settings you need first to click on `Comments` and then by clicking on a text field you’ll gain an ability to allow users to edit own comments. You just need to put a drop-down in the “Yes” status.

Save your modifications with the according button “Save Changes” at the bottom of the page.
