from the ccs forums...

Also a steam problem which is why baz couldn't join other peoples games I discovered is infact due to location. Americans can't play with europeans for instance. It's all to do with where you set your locatrion to in steam so everyone will need to change to the same continent if they want to play together.
so coupled with no apparent general lobby, it makes it hard for the old community to get together and play as in the past.

is this so for those who are playing online?
