• [x] 1. Add the "What are features?" description. The description text:

"We believe that everyone has something unique and valuable to share, which is why we encourage all members to host a feature at our events! Whether it's a new hobby you've picked up, a personal passion project, or just something you find interesting, we want to hear about it. 
 Don't worry if you're not an expert - we value personal experiences and engaging storytelling. We want to hear about your perspective on the matter!

If you want to partner with someone else to make your feature even more special, that's great too!

We can't wait to see what kind of features our members come up with."

• [x] 2. Add the "Host a feature!" button. This button should link to the Google Form
