From what I can remember (most of you probably wouldn't understand me unless if you're an IT/webdev person LOL XD), the old forum was an ASP-markup software. I don't know a lot about ASP pero the only difference I can tell you is that PHP-based software like this new one is one of the fastest-running, it has less bloat, plus it saved ABS-CBN a lot of money because the SMF (Simple Machines Forum) is free LOL. In addition, this new forum system is extensible and it would still run fast even with new features on.
Suggestions? Maybe you can add a small general subjects forum, like anything non-ABS-CBN related. You may never know, ABS-CBN writers may get some ideas for an upcoming teleserye based on the general subjects posts and stories that members share with the community. What do you think?
