Fool chile

Anyone got googlemail? What does it mean when your contacts have green circles against their name? Presuming they mean the person is online and available for nattering and the grey means they aren't, what does the orange circle mean? I am confused because frankly, I am not very bright.

OK, dreadful grammar up there. I apologise. Soon I will do a proper update but for now, may it suffice for me to wish the gallant theoclarke the best of all possible birthdays:-)
