Actually, a point on the "talking during auctions" part:
People chattering constantly during auctions makes it harder for the GMs to run the auction properly.
The more lines of text there is, the harder we have to try to pick out all the bids and actually relevant questions.
On the other side, bidders, at least let Pixie finish telling everyone about the item before you start spamming numbers. Especially before you know the starting bid or the min increase.
