I agree there isn't enough info. Very annoying. I just signed up with a mailinator.com address to see what was in there. It seems they charge 5 cents per minute

I agree there isn't enough info. Very annoying. I just signed up with a mailinator.com address to see what was in there. It seems they charge 5 cents per minute. It's not clear if that is per phone connection or per meeting. They also provide an option to link your Google calendar to the account.
