Can anyone give me invitation for GrandCentral?

I have a GrandCentral account, but I can't figure out how to send an invite. There doesn't seem to be a link when you login ...

Seriously? Trolling for service invites on HN? How is this not dead?

There have to be somewhere in there to invite. Google doing this on purpose. Anyone out there have GrandCentral and can send me invitation?

why do you want to kill it?
