I was invited.. free blogger account too. There was a box just above the login / pick your blog area on the blogger.com main page. (if you don't see it try http://blogger.com/gmail.pyra .. you may have to be logged into blogger.com.)

Gmail will be quite useful for handling newsletter subscriptions like WebProNews. I don't know how many times I started a project and thought "hey I remember getting a tutorial about this from those great WebProWorld people" and not being able to find it.

What else will it be good for?
