## Overview

<!-- Description of what is changed and how the code change does that.
-->
- I dislike that we must create complex, new QR codes for each meeting.
- I am also spending at least two minutes each time trying to find our
Eventbrite when I want to find it.
- I also think it is simpler and more straightforward to give url to ppl
to find our Eventbrite/Discord rather than telling them to find it
somewhere on the website (I know, it is *currently* easy to find, but
still...).
- Merging this means that we will not need QR codes anymore, either.
