We mainly use Discord for our day-to-day communication in the group. Any important announcements, polls or votes will also take place on Discord.
The forum is mainly used for important topics that need to be kept around for reference, i.e. it is mostly used for archiving, feedback and the like.
Teamspeak is our main voice communication hub. Anyone flying with friends, flight trainings, squadron meetups, as well as campaign, all take place on Teamspeak.
