New Article Type

A minor thing but it's something I've wanted for a long time: reference articles. A simple place to post stuff that you use everyday: JavaScript cheat-sheets, ASCII tables, or Pi to the 1,024th decimal place. Hit the Article Submission page and choose "Reference" from the submit menu.

Customise your Profile

Go to your settings page, hit the Customisation tab and you'll see a text area for entering in styles augment or override our basic styles. It's beta, it may break things, but that's what life's all about, isn't it. Enjoy responsibly!

cheers,
