Update 2: Here's the story about Gmail doubling users' email storage capacity.

Update: As predicted below and elsewhere, Google has used the one-year anniversary of Gmail to make a major announcement. Only the news is not of a public launch but that it is doubling the capacity of its free email service to 2 gigabytes. There's also the requisite April fools' gag on the Gmail logon page, in the shape of a "Infinity+1 storage plan".

Thanks for all your comments about Google: I'll be taking a look at them as soon as I've written a news story about this latest development.

8.37am: It was exactly a year ago today that Google launched its free one-gigabyte email service, Gmail with a jokey press release that many people - some journalists included - speculated was an April fool's gag. At the time the idea of giving someone that much storage space for free was so unthinkable that no one could quite believe it was true.

One year on, and Yahoo! has increased its free email account storage to match Gmail's, and the email market is once again competitive, as I wrote in yesterday's Online.

There have been rumours that Google will use the first anniversary of its beta launch to make a public release of Gmail. In some respects, Gmail is already public, because the company has released so many joining invitations for existing users to give to others than pretty much everyone who wants an account can have one.

What do you think of Gmail? How have you used it to help you work smarter? Or are your privacy concerns about Gmail stopping you from getting an account? I'm collecting your Gmail comments, tips and hints.
