Suggestions re Headings, Navigation

On the home page, where it says “Join In” and “Find your community here” it is a little confusing to not have something to click on (e.g. have “here” be clickable or a menu of options for your community). I wonder if the navigation from there could be more intuitive.

Hi team! I am having trouble creating a new topic or conversation. What is the easiest way to see all the existing conversations?
Thanks!
