Don't @ me...or do

It would be handy if when mentioning someone in a post we could click on that person's @ and it would automagically put it in the reply box (like when doing a quote but not necessarily when quoting someone) OR when we start typing @ it brings up a list of members. The more letters you type for that specific member, the less members you get in the list until the one you want is visible and when you click their @name, they are now in the reply box. Just a thought.
