It is worth noting that the forum is now running the latest version of the forum platform (UBB Threads) software; therefore, what you may perceive as missing features are in fact changes with the interface. All the features are present and, in fact, there are quite a few new ones.

You can read the change log here: https://www.ubbcentral.com/forums/
