I'm in... I just replied to my invite and set-up my Google Voice account.
Welcome to Google Voice! Google Voice gives you a single phone number that rings all your phones, saves your voicemail online, and transcribes your voicemail to text. Other cool features include the ability to listen in on messages while they are being left and the ability to make low cost international calls. To start enjoying Google Voice, just give out your Google Voice number. You can record custom greetings for your favorite callers or block annoying callers by marking them as SPAM. Just click on the settings link at the top of your inbox.
Once it's open to everyone, you can join me!
