Hey Amber,
PR means “pull request”, and it refers to GitHub. Essentially it means that Falco made a change to the Discourse code, and is looking to get that change reviewed before merging the change into Discourse.
This specific Discourse site, meta.discourse.org, is updated automatically with every change one of our engineers make. Your site is not deployed automatically like that - we deploy customers on a regular, but less frequent, basis. I’ve gone ahead and initiated an deploy (update) for your site. The deploy should complete in ~30 minutes.
Once the deploy is complete, you’ll need to rebuild the post. To do that, click the “show more” button below the post, then click the admin wrench. Lastly, click “rebuild HTML”
