Gmail opened for everyone

Three years ago, on April 1st 2004 Google announced Gmail, a mail service with interesting new features comparing to other mail services: huge mail inbox (it started with 1GB, it's up to 2,8 GB now and growing!), quick mail search function (based on the great google search engine), a simple UI based on javascript and ajax that made the mail browsing quicker than ever, a labeling tool to organize the mail instead of deleting it (remember, you have no space problem), and a great SPAM filter.
At the beggining, you needed an invitation to use it, there weren't many, so people even paid for them. Then they gave out a lot, and more people started using it.

I created my account on December 2004, thanks to my brother who sent me an invitation, and since then it's the mail service I use, it's quick, easy, and really handy.

Since then to now they have added tons of features, like a WYSIWYG mail editor, a better contact manager (you can even attach a picture to a contact), and the best of all: Instant Messaging through the very Gmail site!! Yeah, that's right, just like Google Talk (no voice), but built-in the site.

Now, you can finally sign up without invitation. Although Gmail remains BETA, it's now opened for everyone to register.
If you still don't have a gmail account, create one, it's worth it.
