Hi Tridip,
Yes, I thought there was an audio alert on the supplier side but I could be mistaken. There are mostly visual alerts that we developed a while back with the help of customer input on what was important to them.
There aren't a lot of queues and, in fact, the customers we worked with at the time were concerned about "too much noise" that would take the attention away from the Auction in progress.
I'll take a look when I have a moment but I'm pretty sure you've identiefied everything there is.
Thanks much,
Rosemary
