OK, first of all, I program fluently in C++ and Uscript, not Java, which PHP is most like. And I pretty much only script online things in DHTML or Java (without taking full advantage of classes).
I'm not really familiar with and new phpBB nor did I study other versions persistantly, so I'm not exactly sure if it's possible, based on what phpBB provides already.
Anywho, there might be a MOD already written for this. And if not, then I might get into Java and PHP so I can satify the online world
