Never played TF2 in my life before, but I’ll certainly download the game and play sometimes (shitty time schedule), if at least a small crowd of people from DB joined, so you could count me in.
As for you being free to play….
I would obviously be FTP too, so I think we’ll get along fine :P
Actually, my friend just bought a gaming PC and I convinced him to download TF2 so we could do something together. We’d both be game if you started a server.
I have no idea how the whole TF2 deal works, I suggest you ask someone who knows about the subject (probably someone you know, or in some TF2 forum or other place you frequent where there are people with knowledge about that), and then tell us, we could try looking for the map like you said, however with an IP is hard to miss.
