You're forgetting (or ignoring) the fact that it's also a
clan league, not a
whichever two individuals are online league. I'm sorry to say but your argument is invalid.

But I think I know what the problem is.
Imagine these two scenarios:
1.) CF has an internal agreement, we all meet up on Ventrilo and join WormNET only as a group when we're all ready and want to play clanners.
2.) CF join WormNET one by one and wait for the others there. As soon as two of us are online people immediately assume that they can ask us to play a clanner and we
have to agree.
It's basically the same thing, yet one kind of behavior does absolutely nothing while the other one makes people grab their pitchforks.
Why do you think this is the case?
