There has been an alert on Facebook about security. It is to do with http as apposed to https.
I notice that at the top of my screen in answerbank it has http. Is this ok? Do I need to do anything? Thanks for your replies.
Secure web pages (with 'https') are only used when you're sending data which you don't want anyone to hack into. (e.g. when entering your credit card details to make an internet purchase).
Normal web pages will show 'http' because the data which you're sending to sites like this one isn't confidential.
