Google sends out another round of invitations for Inbox app
Right now, the app is available via invitation only, as we pointed out. And sure enough, our own Michael H. had managed to wrangle an invite, which he used to pen a "Hands-On" about the app. We should point out that once everyone read Michael's story, people came out of the woodwork emailing him, and texting him, requesting an invitation to the app.
As it turns out, a tweet sent out by Google on Thursday, revealed that the second round of invites has been released, with more on the way. If you requested an invitation for Inbox, you should be receiving it soon. And if you haven't requested one yet, you can send your request to Inbox@Google.com.
