There is a good news for Google Wave lovers as Google has finally unfolded the online based web tool to every one. Google Wave was first announced 6 months back, which allows you to chat with your friends, share your projects, and work at same instance on the project with your colleagues.
As before you need an invitation to use Wave, but now you can sign-in to Google Wave if you already have an existing gmail account. Catch some of the official hearing sentence at Wave launch.
Starting today, we are making Google Wave openly available to everyone as part of Google Labs. You no longer need an invitation to wave — simply visit wave.google.com and sign right in. Likewise, if you are a Google Apps administrator at a business, school or organization, you can now easily enable Google Wave for all your users at no extra cost.
