RAK's are not generally- planned, (random act)
it is not an (event) or a structured activity
anyone at any time can participate (commit a random act of kindness)
you can browse the donations/help wanted sections of forums & send someone something with out expecting anything in return- there are so many things a person can do to just make someone else's moment mean something-be special- be kind- without expectation of reward-or even acknowledgement is what it's all about.
