Thread: Tagging a person

Just curious, is there a way that we can tag someone in a thread and they will get a notification similar to Facebook?

For instance, if I were to mention Gugi or Bruno, it would give you a notification so that you could check the thread to see why you may be tagged.

Lets say someone tagged me in a thread about a razor that I had made & didn't recall the steel or something along that line...then I would see the tag and be able to respond accordingly.

I'm sure it has a LOT to do with the base program we are working in, but wanted to ask non the less.
