Don't know what you mean by round robin but I'm supermod overall so the OTC notifications shouldn't behave any differently from those from elsewhere.
As I said, it's got admin stuffed and it's dragged on for quite a while. Thanks to the mini-avatar thing 'though, there's a workaround so I'm really not-bothered. At this point it's just a curiosity I guess.
Thanks for trying to help Brother 3.
