Don't post anything you don't want the whole world to know.
I want you to connect with other Aboriginal people - so set up a Yahoo! or other email account under a gammin name and get people to contact you through it.
Keep your personal information private - never post your address or home phone. Be careful if calling on the phone.
If you decide to meet with someone offline, discuss it with a friend and develop a plan which includes meeting in a public place and taking someone else along.
