An experimental WoW attendance tracker I created for raids in 2007.
At the time we were using zero-sum DKP with complex attendance rules. Many players were joining and leaving mid-raid, and we wanted to correctly give points full & partial attendance. In addition, we needed to quickly know the DKP ranking by player class and tier when a loot event occured. This tool was used for about 3 months before we switched DKP systems.
It has some serious security issues (like the database password being in a text file in the webroot), but could easily be adapted to be less awful. Maybe i'll get around to it one day.
The database schema in schema.sql is for the core tables - it also assumes you have an EQDKP install with table prefix eqdkp_bees_. It also makes some assuptions about the way you set up tiers in EQDKP. Yeah, sorry.
