Ten years of Discourse! What Discourse communities have you been grateful for?

I just discovered that Codea moved their forums to Discourse last year or so:

I’m so happy because I remember when I first posted on their forum years back – when it was on other software – I remember how painful it was and how much I wished it was on Discourse.

Codea is a coding app on iPad that you can use to make 2D and 3D projects.

It was a community I visited across of couple of months years ago, so not something I visited frequently or long-term. But just wanted to mention this in the broader celebration of 10 years of Discourse – it’s always a joy to see migrations to Discourse. Something I’m grateful for too! Makes it easier for me to participate.
