ContextTree has been shut down

Sign-in is no longer available. The backend for this project has been turned off, so accounts and live features won't work anymore.

The honest reason

I built ContextTree and put a lot into it, but I couldn't get enough people to actually use it to justify keeping the servers running. Rather than leave a half-working product up, I've decided to retire the backend. The frontend stays online as a showcase of what it was.

Thanks to everyone who gave it a try. It meant a lot.
