Hey @GYFX35 - I've reviewed your changes - here's some feedback:

• Wrap the jumbotron title and description in translation functions (e.g. _()) so they’re i18n-ready.
• Consider conditionally rendering the static jumbotron versus the personalized greeting for authenticated users to avoid losing the user’s name on the home page.
