Just want to chime in here. I too agree there are far too many passworded servers. I have all but given up on multiplayer. I have tried passworded servers before but I was forced to use TARS on team speak. It is a nifty little add on but far too hardcore. Additionally people in team speak I have encountered force me to use the military terminology for everything. I know this is a study sim and I like that but there is a point to where it ceases to be enjoyable due to such serious players. A lot of people like that and I understand and it's cool but I just wish the were some more laid back servers.
I rent a server from a company called feral hosting and they provide command line only access to a unix based o/s. I host team speak from it as well as "other things". I wish there was a way to host a DCS server on it. I'd make it a little more laid back (i.e. radio communications). Oh well, I do find a great server that is unlocked with great and less hardcore people every once in a while. As for now I'm trying out the campaigns. The default built in one is pretty repetitive. I'll check out the other ones that were removed to see if they are any better.
Again, love the game, just too many passworded servers where people act like its life or death.
