A post older than 24 hours is considered stale on this forum, eh?
What makes you say that?
Server passwords protect players from jerkwads and griefers (like the guy that played demolition derby with me on the taxiway that one night). Put the Teamspeak info in the mission description and decent folks can hop on and ask for the password.
Much as I don't like being "elitist" in any way, I would strongly campaign a password-protected server for these same reasons. BTW, note that the SimHQ TS3 details being shared by posting it on the mission description is considered a "no-no," as I recall from conversations with WC during one of the Fly-Ins. Can't quite remember why, but it was how the SimHQ mods wanted it and WC respected that request. So the only way they can come it is to sign up on SimHQ, find the TS3 details, then hop on to the server. Or even just come onto this thread and discover the password.
