Oh I forgot to mention, there are some PR naming conventions that this repo follows to differentiate recruitment platform PRs and other BP website update PRs. See this Notion doc for more details: https://www.notion.so/uwblueprintexecs/PR-Commits-Grooming-Guidelines-a9e70702b8484557b568d811f0f4ef58?source=copy_link

Otherwise thanks for doing this!
