A few comments!

We will want to have well-organized files moving forward - and although a single folder technically works, I think we should perhaps organize using the same structure as the posts so it matches, 1:1. E.g. for the post _posts/tutorial/2022-07-07-radiuss-on-aws.md it would be under assets/posts/tutorial/2022-07-07-radiuss-on-aws/RADIUSS_tutorials_flier_final.pdf That should make it stupid easy to find files matched with different kinds of posts.

We should generally use css elements for buttons / other interactions and not images - e.g., so let's please remove the tutorial button and have it be something like:

<a class="btn btn-primary btn-lg" type="button" href="https://forms.gle/3wAKK5PBizUiNaVg6" alt="Sign up Button">Sign Up</a>

(and choose the styling that you like!) I would add some padding to the top/bottom so there is a bit more white space around it (it looks cluttered in my testing but this looks okay):

I'll put more comments alongside the changes!

Sorry @vsoch one more (the 10th) commit to add the radiuss-outreach email address as a way to contact. I was able to confirm today that I accepts emails from external-to-LLNL people. So the page looks like this:

Thanks for your feedback & patience
