I pitched it almost a year ago and it's almost the exact thing you're describing, and basically includes the following.
- an option in User CP or on an individual post that allows you to select "Notify me if my post is quoted"
- There is already a portion of User CP for subscribed threads, there can also be a second for quoted posts.
- When a post is quoted, and the user has requested to be notified, the "Quoted Post" section in their User CP gets updated.
How it can work?
The quote button is set up with:
http://www.overclock.net/newreply.ph...reply&p=######
Where ###### is a post tied to a particular user. When the quote is clicked, why can't there be a portion of code in the newreply script that updates the "Quoted post" section of the user that created post ######.
It's seems like an incredibly straightforward implementation because it is event-driven only when the Quote button is pressed.
Edit: It there would have to be something in place for the case where the quote button was hit but an actual reply wasn't completed (as in the case of accidentally pressing the quote button).
