Welcome. Off-topic is a board meant for less-than-completely-serious debate, idea sharing, news linking, et cetera. All these things which get posted in Discussion, but which most members that participate in Discussion don't really feel that they are suitable to a forum of the type Discussion currently is (Read: Debate). This means you can post some stuff you find interesting or new or cool here.

Now, Off-topic, like every other section of the main forum, has some simple common sense rules.

Firstly, this is not Wibbles.
Secondly, anything that would get you banned in Wibbles will get you banned here on principle.
Thirdly, don't post anything you wouldn't say to your awesome grandmother that makes those super delicious chocolate chip cookies.
