With the advances in modern technology, computers can actually recieve and transmit the electronic pulses created by intense thought patterns.  If you want to answer a question here, all you have to do is lean close to the computer, close your eyes really really tight, and think as hard as you can about the answer you want to give.  The computer will take care of the rest.  If it doesn't work the first time, just lean in closer and think even harder.
