Under construction

This is a test of golf server. You can enjoy short coding here in several languages (69 languages). The purpose of this server is not serious competition. Joke problems are welcomed and you can speak freely about problems and can release spoilers. For serious competition with ranking, enter Code Golf.

IRC channel for this golf server: #anagol in freenode. Please feel free to join the channel to talk about various things around golf.

Mark Byers kindly prepared a site for this golf server. If you would like to join to add tips, please ask Mark to add you as a collaborator (supposedly, in IRC?).

I've just understood how to create too short entries (thanks for nazo). However, it seems not to be easy to fix the bug. I'll work on the problem in near future and I'll remove entries which is considered to use the bug. Thanks for understanding.
