Merging user accounts is a confusing process. It is difficult to know which user account will become the 'parent' or dominate account especially if the user accounts share the same name. Even though the tool asks you to verify it is often still unclear which account will end up being the dominate account.
I have chosen to merge from student 66666666's account however, student 55555555's account will be dominate account, but there is not way to tell that from this screen.
I would love to see this tool be made clearer, so it is easier to verify which account will merged into another.
