If you live near the Climate Change camp, and have wifi, you can help the Climate Change protestors out by switching off your wifi password. It’s not that risky if you have decent security software on your PC, and its firewall is enabled – see this explanation.
Amelia Gregory, one of the organisers sent a message out, saying:
Well that was good. Have been totally unable to get online all morning til I discovered we have wi-Fi. Are police blocking me?!
Doubt they are being blocked, probably just a zillion wifi users all trying to connect to one router!
