Hello Steven,
Thank you for your question about Auction Tribune alerts. The short answer is that we recently revamped this tool, and you found a glitch. The alerts are turned off until we release the patch, which will probably be middle of next week.
Thank you for letting us know about this. We try to be very responsive in terms of suggestions and tweaks to the site, so please let us know if there is anything else we can do to improve your experience.
