^ If you've moved and no one involved either knows or are able to find out your email address or new home address, they won't be able to send you an invite. My cousin was on her reunion planning committe and she said it was a ton of work just trying to find out where people moved to, if they'd died, etc. This was 20 years ago, so it was pretty much all phone calls and mailing letters, but I'd imagine it's still a good amount of work to get contact info.
