When Google asked what you liked and disliked about their new real-time communication application, you unquestionably said that you wanted more invites to share with friends and family. Problem solved!

Today Google decided to play Santa with Wave invites. It has just doled out significantly more invites to existing users.

In conjunction with the invite rollout, Google is also hinting that they’ll soon reach the 1 million user mark. The title of their post suggestively hints that “a million stamps” have been licked, which we take to mean that they’ve now opened up Google Wave to a million users.

While invites may be more readily available, be forewarned, Google is still not ready to graduate the service from preview phase to beta stage. Still, we’re excited that more of you can get in on the shared experience that is Google Wave.

Confused about how to use Google Wave, the new Google product that combines messaging, wiki-like features and group collaboration into a single app? You’re not alone.

Now Gina Trapani and Adam Pash have gone a step further, releasing The Complete Guide to Google Wave. The book, which is available for free online, details all of Wave’s features – and some use cases – in 8 chapters. It’s a super-handy reference if you’re still stuck on how to get the most out of Wave. Recommended!
