What happened to email? Isn't that a system which can be used to 'organize all sorts of events'? It's worked very well so far.
Disclaimer: I am not and never was on Facebook, so I am clueless.
@jpmens @bortzmeyer Emails are very bad for having an overview in one glimpse of participant/interested parties count, and to assign roles (leafleters, guardians, mouting/unmouting stands, etc.). Emails are not very good to create galleries of photos of a particular event. And these are only examples.
