Hi Rob, thanks for your thoughts! We're not planning on expanding to watching expiring domains yet, we're focused more on finding domains that were never registered. But what you're interested in can be done by watching all the registered domains that you're interested in and either catching them when they expire (ex. https://www.expireddomains.net) or by registering a backorder (higher success rate but you have to pay, ex. https://www.gname.com/backorder)
