Maybe I am blind/having a blonde moment, but is there a way to be notified of someone quoting a post without having to individually enable notification for each individual topic we post to?
There isn't a way just to notify you if there is a quote.
However, if you want to enable notification on all topics you respond to, here are the steps to do it:
Profile > Modify Profile > Notifications > Then click the box infront of "Turn notification on when you post or reply to a topic.". Then remember to click the "Save Settings" button after you do that. ;)
That way, every post in the future, you'll be automatically notified by e-mail (if your e-mail here is correct of course, lol) whenever there is a new post in that thread since the last time you viewed it. :)
