In all seriousness, it is hard to believe that much time has passed (not the 25 years that passed in Jumanji, but still).
I'm not familiar at all with how such a thing is organized. Are there people already in charge of setting it up? How do they get in contact with people (particularly those that have changed addresses numerous times in the intervening years)? If it's through Facebook, how are they assured that somebody (like me) isn't trying to disrupt the possibility of being found in some crusade for Internet privacy? Will there be a time and place for a dance number?
Anyhow. Sorry for not being helpful. Already having to take measured breaths, and it's more than a year out.
