People are going to get linked to this forum sometimes, even when they’re not familiar with Rust. If they want to know about it, the natural choice is to click the logo in the header to go to the home page. The forum’s home page still doesn’t tell you what Rust is, nor does the pinned announcement at the top, but we probably do want the forum to primarily serve as a place for people who’re already trying to use Rust.
What we really want is for newbies to end up on the home page. It’s possible, using the “Customization” options, to add navigation options to the top of the forum, probably a duplicate of the nav items on the main page with “Community” highlighted to put u.r-l.o into context.
