If the other users are tempted to socialize, they will be here on forum.
If they don’t read the forum, probably they are not into socializing, I wouldn’t bother to reach them.
So I would open a thread with the title related to your area (closest airport, geographic region) and asking people to join in that thread. Like a “chapter” or a “club”…
“Greater St Louis, MO area club” for example. Or the whole state, if works for you (won’t for me). Or some other smarter name you can come up with (I might copy it)
