I just installed the Discourse Cakeday plugin here on the Guild.
That means you’ll see the cake emoji () next to your username on the anniversary of you joining the Guild.
It also means you’ll see the birthday emoji () next to your username on your birthday. But that requires you to fill in your birthday in your user preferences. Scroll to the bottom of that page, fill in the month/day, and you’re set!
Finally, you can see any upcoming anniversaries/birthdays by clicking on
Cakeday in the hamburger menu.
