WhatsApp groups used in all our comps, pics of gridlists, tasks etc. distributed smoothly to everyone (plus SoaringSpot, where you can download the task straight to devices). Printed papers available for luddites, of course, you don't want to mess with them as they just were forced into GPS-age.

I am not a Luddite, have used GPS for 20 years and LORAN before that. I have a smartphone and use IGCdroid and GliderLink. But I have a healthy suspicion of the mega-corp spyware. To repeat one of the comments quoted by Jamie to start this thread: "why not stick to the standards, SMS text messages, email, and a web page (a real web site, please not Facebook). Put downloadable documents (task sheets, weather forecasts, grid sheets, etc) on the web site. If they are suitable stand-alone files (PDF, JPG, PNG) they can be downloaded into the mobile devices for later off-line use."

In an International competition, not everybody will have a "local" phone. In this case SMS / text - particularly with attached media - costs significantly more than using something like WhatsApp.
And I hate Facebook (parent of WhatsApp) too.

I also hate Facebook, but WhatsApp is a great app.

If you're worried about giving away your phone number and contacts list to FaceBook then Telegram is a great alternative. Its author, Pavel Durov, is a privacy and freedom nut (in a good way). He made vk.com, the "Russian Facebook" and then when the Russian government basically stole it from him he (and his brother) exiled themselves and set about making Telegram.

On Telegram you can let people contact you either by account nickname or by phone number. You don't have to tell the app your phone number if you don't want. Like WhatsApp it works well both in a desktop browser and in the mobile app. It's got end to end encryption good enough that it simultaneously ****es off the Russian authorities because they can't break it AND both lawmakers and dissidents trust it to protect their privacy.
