The organizer (s) of my HS reunion. Apparently there is one scheduled for next fall. But right now, the info is ONLY only classmates.com, which is had to register for to see the info. And I only knew something was even planned because someone else asked about it on FB. I wasn't the only one though, and the initial asker contacted the organizer, who said she's working with some company that plans them, and info etc will be on FB shortly.
Grrrr. And out of 500+, only half were "invited" via the classmates invite. Thankfully I'm local, and it's actually close to where I live now, which is about 45 mins from where we lived. But I have to wonder about those who need to make travel arrangements, if they don't know, and don't find out for a while. Personally, I think they should have used several channels to get the word out, even if only just the date and location.
