Disable sleep mode when closing Macbook lid?

InsomniaX and Caffeine are two applications you might like.
Found via search for "disable sleep macbook"

May I ask what for? I'm always intrigued by people that want to close the lid with the computer remain awake(unless we're talking clamshell mode).

Do you mean you want to use it in clamshell mode?

Caffeine won't keep your MBP awake with the lid closed. To do that, use InsomniaX or InsomniaT (rebuild for SL) (fix for 2011 MPBs)

It was such good advice it deserved an encore.
