If you need to get in touch with us, please see our contact details.

Traditional Access

We love to support our users who live in the 1690s or are otherwise allergic to electrons, so offer a number of traditional access mechanisms.

Chaos Post

A paper copy of your results may be requested by sending your account name and return address to:

ECS Village
Flux Passage
Electromagnetic Field 2024

We also will reply to letters sent via Cutel Telemessage.

In Person

Visitors to our headquarters may request a copy of their results from a volunteer. Bonus points may also be available from our HQ.


Semaphore operators should signal G C H Q N E T, followed by their account name.

Japanese semaphore and RFC 4824 are regrettably not supported.
