Don't take this personal Norm, but if I recall the little discussion on this topic there were more for JoinFS for obvious reasons and TeamSpeak. You say Discord has more features than TS, but that isn't exactly so. True you can"t post local pictures unless you upload them in TS, but if you use the free printscr service you can. TS has a file storage/retrieval system that works well. FDHost is nowhere even close to JoinFS, period.
Now as far as utilization, I know of only one or two flight ventures since implementation. I fly daily on my JoinFS, with or without anyone else. This can also be used while flying alone or in groups, joiners choice. I'm not in competition, just offering a regular daily choice.
I was just up on Discord, saw four of us online, but no one in the chatrooms.
