I love Gmail. I think it is the most beautiful thing to happen to webmail ever. Now, it is getting better. Apparently, Google is going to begin offering 2 gigabytes of free space (Yahoo and MSN have the 2 gb option, but it's not free).
For more information, follow the geek.
By the way, I have hundreds of invitations to give away. Just click on the Gmail button on the left menu and you shall receive.
