      ![The Virus Lounge](/static/virus_lounge.webp)

      Welcome to **The Virus Lounge**. We're a random group of
      people who feel undersocialised in these trying times, and
      we've decided that there isn't enough spontaneous socialising
      on the internet.

      ## Where did all these people come from?

      It's pretty straightforward. Feel free to click on people, too.
