Discord for sure does seem to be among the most used method I've seen here, and I'm not against its use. I'm just old school I guess and prefer to visit an actual website to learn more about the possible squadron I might be interested in. (And I'm also from the Teamspeak era, for that matter ). It just seems easier to me that way, rather than joining discord for a squadron, only to realize it probably wouldn't be a good fit.
Good example is your sig. I saw your website link and went to it immediately.
Just interesting to see exactly how much things have changed over the years
