====================

Yo, it's the front page.
|
|
|
|
|
There's stuff you can do here:
|
|
|
|
|
|
|
|
|
|
* [Available puzzles](/puzzles)
|
|
|
|
|
* [Raw filesystem view](/files/)
|
2016-10-21 14:38:19 -06:00
|
|
|
* [Documentation](/files/docs/)
|
|
|
|
|
* [Instructions](/files/docs/devel-server.md) for using this server
|
2016-10-14 22:26:47 -06:00
|
|
|
|
|
|
|
|
If you use this development server to run a contest,
|
|
|
|
|
you are a fool.
