It is by far one of the easiest hacks to install and the easiest one to modify.
For my UBB, I allow the user to select a race/class in their profile. Within the ubb_library2.pl file, I compare their selection against the number of posts they have. If they are a Dwarven Fighter with 21 posts, they are level 2 with a dagger image. As they continue to post, they gain higher levels and their personal equipment changes.
It's different for each race, elf, halfling, dwarf, human, half-orc, drow, half-elf and contains fighters, paladins, anti-paladins, rangers, sorcerers, wizards, bards, monks, priest, druid and rogues.
The potential is endless! HAVE FUN WITH IT!
