Back in February, I shared a project I'd worked on that allows me to make posts/comments on SN via custom-written code. I use it when making my mining comments on the daily saloon thread. You can read more in #443617.
With the recent release of API Keys on SN, I've updated the code to use API Keys instead of cookies. This greatly simplifies a lot of the code.
Take a look at the code here if you're interested.
Thank you @ek for adding API Keys!
