I don't care about dc or omg, (except for f@#!in italians) I just wanted to say you that there is a module of wormkit called Wormnat2. With this module you can host also if you have some problems with yr router etc... I think this is the reason why you usually host with hb. Then, download wormnat2 and host every kind of scheme you want and maps, as everyone.
It's correct that when you turn up the light you agree with the scheme, even if I think that if you put some variations you have absolutly to advertise the opponent before the game starts. Hosting with the buddy maybe could present some of those risks. Then use Wormnat2 and right scheme or advertise before the game starts.
This is a mature way, not all of yours.
look for it on
