Most of you have used Facebook, most of you are familiar with what typing the '@' symbol does right? Well, why not introduce that into Xenforo as well? This way we get alerts for quotes and for people including us in a thread or reply. Essentially tagging people in posts.
Here's an example scenario, as a site Administrator I find it happens all the time.
Members are posting questions in a thread you recently posted in and are asking you a new question or something. What if they didn't wanna quote you as their question didn't pertain to what you said? Or how about someone is making a new thread and they would like a specific person to be said in the thread.
On bigger forums this might prove to be annoying, but I think this would be great on medium to small sized forums. What do you guys think?
---- Xenforo wouldn't have to use the same thing Facebook does, maybe there could be a bbcode type system involved. I would expect Xenforo to make it more modern and have a search bar appear to aid in finding the person wanted.
