So whilst browsing PbN and finding my name being mentioned about a month ago in a thread I was fully unaware of, it struck me that a twitter/facebook style "@name" system that will bring up a drop-down of users and then alerts them as to when they were mentioned would make for a more pleasant end-user experience.
For example if I type @Drex17 it would autoformat to
Drex17 and below his subscribed threads in the UserCP panel, list of "Threads you were mentioned in" could be displayed.
Just a thought for this ever improving site, thanks for taking the time to read it over!
