Hi @partapparam,

• Pull request is done with the correct branch.
• The issue is linked properly.
• Pull request has the proper title and content with a single suggestion. The part where it says "Why did you make the changes?" could be more descriptive. A good guide would be to use or reference the Overview from the linked issue, for this case: "We need to create a single variable github-handle to hold the github handle for each member of the leadership team. Eventually github-handle will replace the github and picture variables, reducing redundancy in the project file."
• Action items from the linked issue were done properly.
• Everything else looks good!

Thank you!
