RaidNinja is a raid management (for any class-based raiding game) system for the web. (There has some been initial work for an in-game addon and/or to tie it into the in-game calendar but it wasn't completed)
Ferby and I, the only two devs on the project, haven't played WoW for quite some time and are looking for some people to pick it up who would still be getting use out of it. I, myself, haven't played since the beginning of BC.
If there's a current project that does something similar and you'd like to merge some code in from RN, that would also be awesome, but please let me know the project or stop by the forums so that I can give our current users a heads up and give them a place to go!
