glitched.systems is a community infrastructure project run by Abhiram so that he can provide a suite of self-hosted tools and services for him and his friends.
There's no real plan on opening up public registrations to any of these services at the moment, mostly as a way to reduce moderation overhead. However, in the future, we might consider opening things up a little more.
If you're a current glitched.systems user, consider donating to help keep the lights on. •ᴗ•
