Yeah the Microsoft Flight Simulator Discord is where you want to be. We’re using that for all text and voice chat, to meet up and organise flights. Just jump in one of the Terminal or Flight voice channels if you want to join in, people will let you know where they are at and how to join, typically you just need to make sure you have the sim set to ‘all players’ and one of the servers (e.g. US East). Then you will be able to look at the airport on the world map and see the green dots of the group flying around.
I’m around most nights, I usually post current flight details in the multiplayer-discussion channel or the specific text room for a voice channel. so look out for that. There’s pretty much always a group doing bush flights or similar, don’t be afraid to join a channel and ask some questions
Here’s some pics from our final flight last night, Grand Caravans in Papua New Guinea - https://imgur.com/a/Vtpzpcu One of the best places to go bush flying, hundreds of really challenging and astonishing little airstrips sitting on hilltops or down in the valleys, often there’s no going around, you have to commit! And the updrafts/downdrafts in that area were just unbelievable, amazing scenes.
Multiplayer in this is hugely good fun, landing on mountains together is a fantastic and memorable experience.
