ive been having problems with router recently and keep having to find someone else (that i assume has correct port settings) to set up a game so i can check that i can join sucessfully. i also see many many new players coming in and not knowing why they cant connect to a game...
a button on the client the tested whether the correct ports are open would make this process so much easier, maybe even something that checked whether the correct version of ta is installed with all standard add ons so games didnt start without commander on screen or without fark etc.
i dont know how easy this would be to add to the client, but i think it should save alot of people a few hours
