Trying to find the best tool to get a bunch of people organised and sharing knowledge can be a pain. Google Groups can feel exceedingly complicated. Facebook cares little about your privacy. And if you're still using Yahoo Groups ... why? Instead of the Big Three, consider a service like Groups.io, a sensible, free platform that's incredibly easy to use.

Last year, Yahoo revealed that it had suffered not one, but two, data breaches that resulted in well over one billion user accounts being compromised. The problem was that Verizon was in the process of buying Yahoo's web assets for US$4.83 billion and there were fears that it would renege on the deal.

In December last year, Yahoo admitted that over one billion user accounts were hacked. It looks like thousands of Australian government officials were among the users that had their Yahoo email addresses, passwords and other personal information stolen.

Last week, Yahoo revealed it had been hacked and information on one billion user accounts had been stolen. It appears that the hackers had put the database up for sale and it has fetched a handsome sum of money.

Stolen Yahoo account information includes hashed passwords and personal information.

This new Yahoo data breach is separate to the state-sponsored hack the company reported back in September where 500 million user accounts were compromised. Read on to find out more.

A new report by The New York Times reveals the extent to which Yahoo didn't really care about its user's security, instead focusing on products and new features.

We've written a lot about how to make the most of Google's Gmail and Microsoft's Outlook services but it's time to shine a light on one of the lesser known email providers: Yahoo Mail. While its popularity lags behind its competitors, there are still millions of people who have a Yahoo Mail account. You may be one of them. Here are some tips on how to optimise your Yahoo Mail account.

Android: You've been able to add email accounts from Yahoo or Outlook into the Gmail app on Android for a while, but starting today, Google's giving those third-party emails access to all the bells and whistles in Gmail too.

Yahoo7 has launched its Mobile Developer Suite for Australia and New Zealand that contains tools to help local developers promote and monetise their apps. Here's what you need to know.

Ever get the feeling you're never going to reach the end of your to-do list? According to Yahoo! CEO Marissa Mayer, that could actually be a good thing.

The news that Yahoo! is to close down AltaVista on 8 July was greeted on the internet with shock. Shock because everyone over the age of 30 thought their original search engine of choice had ceased to exist years ago, around the time dial-up went out of fashion, while anyone under 30 struggled to believe that anything had existed at all before Google.

Yahoo! announced recently that it will be resetting all Yahoo! IDs that haven't been used for over 12 months come July 15. The move is an attempt to let new users get access to unused logins.

Yahoo! has acquired Astrid, your favourite to-do manager and one of the best for Android. The company hasn't explicitly said Astrid is shutting down, but the language from Yahoo!'s blog post doesn't leave much room for hope. If you're an Astrid user, it's time to look for alternatives.

A link exploit has been found by Yahoo Mail users that can compromise your accounts. Here's what to watch out for.

We're not big fans of Coles' flybuys loyalty scheme -- earning points takes ages and you give up lots of personal information in the process. The recently introduced flybuys Toolbar takes this to a new level of intrusiveness, promising you can earn points "just for surfing the web". Perhaps -- but you'll give up even more information while doing so, and get a maximum of 50 cents a month for the dubious privilege of using an inferior search service.
