If anyone has heard of KGB, then this might be familiar to you. Cha Cha is a free alternative to KGB (which I believe makes you pay $20 to start and $.99 a text). If you don't know, KGB and Cha Cha are question answering numbers you text. You ask it a question and it sends back an answer. There are downsides to Cha Cha. It has some ads on the texts, and there is a limit to how many texts you can send in a certain amount of time. But other than that, it works very well. It's a clean and quick way to get some questions answered that come to you while away from the computer.
