just wondering how active the open ladder is at the moment, like if u challenge someone will they actually accept?

You'll find both the leagues are locked for this season and you won't be able to signup.
The CGo ladder will re-open in November, what I've been told.

You can keep track of the other matches here,

Isn't he talking about ET?
It's in the ET section?..

For some reason this thread disappeared for a minute. And so did my comment. Yes he is talking about ET, that was my bad, clicking on too many recent CoD threads and this got thrown in there.
