Yes I only email directly with the lot numbers and bids, that's good enough. If you've not registered before you'll need to add a delivery address too.
I think in the event of the same bid, the earlier bidder will win the lot if that ends up being the highest, but don't hold me to that.
Also you can't bid or listen in live, however there might be the possibility to watch the lots go on the saleroom but I'm not 100% sure if it works.
