# What does this PR do?
This fixes a wrong suggested tag of a Github user not acquainted with this project to the correct contributor. 

#### Personal Note
I can definitely see that his and my username seem switched given our clear names and I'm sorry for any confusion. That username was given to me by a teacher in school who didn't want to spell my full last name and it stuck.
