QRP is usually defined as operating using less than 5W of power. Most QRPers operate CW but some use SSB and other modes too. Why operate QRP? Some like the challenge of being able to contact a DX station using only 5W or less while those around them are operating 100W or even 1kW, others get into it because you can build an entire station with a QRP transceiver kit at the heart of it while otheres ...just like operating QRP!
You don't necessarily need a QRP kit to operate QRP, if you can reduce the power on your rig and check it out with a meter, then you too can operate QRP. So this month try operating QRP and see what you think of it.
There are tons of QRP groups and links, below are some of the groups I belong to, have bought kits from or ones that has tons of links to other groups. If you have a favorite that's not listed, let me know.
