rtpHarry:Couldn't get it working though but from this thread I guess its actually broken and not just me being stupid.
You are right, it's broken (i.e. it's not you, it's us(. The problem is that we have moved to ARR for load balancing, and ARR does not work with NNTP. What we are going to do is introduce a new domain for NNTP use. We are working on this and are trying to have it in place ASAP.
