When Google bought out GrandCentral, they took the product into beta and have just begun sending out invitations for beta testers.  I got accepted and got my invitation this past week, they’re working on a model simiar to GMail, in that I have a few invitations I can give out.  If anyone is interested in one just leave me a comment and a reason why I should give it to you in particular.  Assuming that anyone at all is interested I will take a look and send out invitations next weekend.  You could always go to EBay and pay $1.00 for one if you want.  I’ll be doing some more writeups about Grand Central as I play with it over the next few days, but the service gives you a local phone number and then you provide it with all your other phone numbers and when people call your GC number you can get amamzing control over what happens to the call.  The most useful thing is that you can have all your phones ring when someone calls your GC number, so you can use your landline when your at home and never waste your cell minutes, and your cell phone when you’re out and never miss a call to the house or office.
