I realized today is the 5 year anniversary of Tiddlyhost.
It wasn’t announced publicly until a few days later, but I can see the very first users and sites all have created timestamps of Feb 12, 2021.
To reminisce a little, I think this commit is the moment when there was a real working production Tiddlyhost server for the very first time.
If you’ve ever been a user of Tiddlyhost, a suggester of features, a reporter of problems, or if you’ve ever made a donation, become a subscriber, been an early adopter, or shared some kindness and encouragement, thanks very much! 
As Michael Stipe once sang, where does time go?

Ps, if you have any suggestions for how to commemorate or celebrate this occasion, please share!
Pps, I am currently working on BYO domain support, which I’m hoping to roll out some time before the 6th anniversary of Tiddlyhost.
