Google has made it possible to send larger attachments using Gmail - and opened the service up to anyone who wants an account.
The company last week increased to 20MB the size of attachments it is permitting Gmail users to send using its free email service, raising maximum size from its previous 10MB top setting.
In related news, the company has also developed new software to make a Gmail user's personal calendar accessible using their mobile phone.
The company has also begun working to integrate YouTube support into Gmail, and has updated the built-in Chat application in order that it now shows you if a new message has come through while you are writing a response to that message.
Finally, anyone can now sign-up for a free Gmail account. Until now, users have required an invitation from a Gmail-registered friend.
The company explains: "You can still invite your friends to enjoy Gmail's spam protection, 2.8GB free storage and other great features, but now you can also just tell them to visit www.gmail.com and sign up without an invitation."
