The choir decided it needed some sort of group calendar, so I hunted around and found phpGroupWare, which shows great promise as an alternative to Micros~1 Exchange.
I've found myself getting involved in the development thereof - so far, at least, by breaking it and finding bugs. It's been a fascinating experience watching the project develop and grow, from the inside, so to speak. I've suggested an idea or two which have been incorporated, which is gratifying, and I'm actually coming up to speed on the code. Actual code! Aiiieeee!
Work, such as it is, continues at the Cthonic ISP with the soul-searing, non-Euclidean machine room.
